The possible solution that I previously posted doesn't require you to modify the volume name. Don't change anything. Just replace Macintosh\ HD by your system volume name in the touch command.
For example, my system drive name is "Lua". The command to input in Terminal would be:
touch /Volumes/Lua/System/Library/Extensions
The solution by RusFox tries to move supposedly incompatible third party extensions to another folder to be ignored by MacOS. You may or may not have these extensions installed. Same goes for the removal of the Eltima extension.
I believe that there is something wrong with the new system Installer and assume it is not rebuilding the extensions cache correctly.
In order to speed-up the startup process the Mac builds an Extensions cache file based on installed kext files. If you add or remove Extensions (.kext files) the cache needs to be rebuilt. The system should identify incoherent cache and rebuild it on startup.
Therefore, I changed the modification date of the Extensions folder with the touch utility. This is an indication for the MacOS that the cache may not match the actual contents Extensions folder and force a cache rebuild.
This worked for me, and a few more users 🙂
