MacOS Big Sur 11.0.1 (20B50) _BEST_
The rollout of Big Sur came with several problems. Upgrading to the initial public release of Big Sur (version 11.0.1) bricked some computers, rendering them unusable. Many of these were 2013 and 2014 MacBook Pros, though problems were also observed on a 2019 MacBook Pro and an iMac from the same year. The initial rollout also disrupted Apple's app notarization process, causing slowdowns even on devices not running Big Sur. Users also reported that the update was slow or even might fail to install. macOS Catalina and Big Sur apps were taking a long time to load because of Gatekeeper issues.

In the comments an article was mentioned that reported that 11.0.1 might have been intentionally blocked for certain MacBook Pro models because it caused lasting damage (Thank you @Tetsujin & @bmike):
It's not clear why Apple has released a new version of macOS Big Sur 11.0.1, but 11.0.1 is the launch version of Big Sur on all Macs except for M1 Macs. Those who have already updated to macOS Big Sur will not see this update, but those who are coming from Catalina or an earlier version of macOS will get the new release.
I noticed from the report that a beta Big Sur 11.1 was installed, then followed by two differently named Big Sur 11.0.1 installations. You may be retaining some of that beta code in the current installation, and that may be contributing to the instability and crashes.
macOS Big Sur made its public debut on November 12 with a version 11.0.1 release. Its launch was marred by server and installation issues, while some older 13-inch MacBook Pro units were rendered unusable.
After testing and experimenting with various macOS Big Sur 11 Beta versions, Apple has now officially released the latest "macOS Big Sur 11.0.1 Final Update (Build # 20B29 / 20B50)" for all Mac devices. If you are wondering where is macOS 11 version? then let me tell you that v11.0 has been skipped and Apple has directly released the all-new macOS 11.0.1 Final Update for free upgradation and installation on supported Mac computers and laptops. Apple has also released Safari v14.0.1 web browser update with new features and functions. All the latest system and software updates are instantly and freely available for all compatible Mac devices on Mac App Store.

We have (at least) two users who were auto-upgraded from Sophos Endpoint 10.0.1 to 10.0.2, whose Sophos Endpoint is being auto-downgraded back to Sophos Endpoint 10.0.1 and then auto-upgraded to Sophos Endpoint 10.0.2. (One user is running macOS 10.15.7 (19H15) and another is running macOS 11.0.1 (20B50).)
Although it isn't clear what's different in the new macOS Big Sur build, macOS 11.0.1 was the launch version of Big Sur for everyone Mac except those equipped with an M1 chip. Because of that, the 20B50 build may have under-the-hood improvements exclusive to Apple Silicon.
Since i've updated to MacOS Big Sur (11.0.1) my Application starts up, the window where the map should be stays grey and the application terminates with a Segmentation Fault as soon as i click the window with the map.
macOS Big Sur, or macOS 11, is the seventeenth major release of macOS that was released on 12 November 2020. It was announced on 22 June 2020 at WWDC. It is the first version to support the ARM-based SoC architecture of current Macs. It drops official support for Intel HD 4000 GPUs, though they work as they did in Catalina. This version has no 11.0 release for Intel-based Macs, even though the OS's beta-testing phase began with said version number, instead, the public release for Intel-based Macs jumped the version number to 11.0.1. Version 11.0 has been pre-installed on some early M1 Macs, and Apple recommends that users running this version must update them to 11.0.1.
Apple ha actualizado la versión 11.0.1 de Big Sur para algunos usuarios. Tras el lanzamiento oficial de esta versión el pasado 12 de noviembre Apple ha lanzado una revisión de la misma con corrección de errores y mejoras de rendimiento, aunque aparentemente solo para algunos usuarios.
Desconocemos los detalles exactos de esta nueva versión, pero Apple ha actualizado la versión 11.0.1 a la build 20B50. Suponemos que para la corrección de errores y mejoras especialmente de la instalación y de rendimiento.
The environment variable SYSTEM_VERSION_COMPAT can be used to control which version of the file is returned; SYSTEM_VERSION_COMPAT=0 cat /System/Library/CoreServices/SystemVersion.plist returns 11.0.1, whereas SYSTEM_VERSION_COMPAT=1 cat /System/Library/CoreServices/SystemVersion.plist returns 10.16. (Note that there should be a space, not a newline, between the assignment and the invocation of cat, such that the shell sees this as a transient environment variable assignment rather than the assignment of a non-exported shell variable).
Apple a discrètement commencé à distribuer une nouvelle version de macOS 11.0.1. Numérotée 20B50 en lieu et place de la 20B29 disponible depuis la semaine dernière (c'était la version finale de macOS Big Sur), cette version supplémentaire n'est manifestement proposée qu'aux utilisateurs dont les Mac sont sous macOS Catalina et qui s'apprêtent à faire la grande bascule. Pas la peine d'essayer de récupérer cette nouvelle mouture si vous êtes déjà sous macOS 11.0.1 (20B29). 041b061a72
