Interesting, I also thought this was resolved, but have found that after working for a full day, it seems it might not be resolved.
Also the Ransomware protection theory seems to bear out what I have experienced. I'm using Visual Studio and when I build larger project Visual Studio seems to 'hang'. After a few tests, I saw the MWB was to blame and when I closed the program Visual Studio continued with the build.
Obviously, if I build large projects are multiple projects, a lot of files get erased and recreated, so this seems plausable. Today I'll disable the ransomware part and see what happens.
