So, it appears that on monday or tuesday the "Command Line Tools for xcode 11 beta" were in the public update channel. And shown in the system update utility of mojave.
I did not payed attention to the version and installed them. Which was a huge mistake. Because now some applications are not working anymore. Especially `mono` applications seem to instantly crash. I guess because the CLTools change some mono lib stuff.
Now I tried nearly all instructions on how to remove them. From deleting `/Library/Developer/CommandLineTools` to completely uninstalling xcode and reinstalling it.
Without success. I guess that somewhere something is still messed up. Is there a proper remove utility or instructions on how to cleanly remove everything ?
This is an unacceptable state currently, because I am in need of the applications that are currently crashing due to the falsy update.
