Hi Pokestuff, if it only happens with Blender versions newer then 2.82 than you might have this issue:
Some people got rid of the problem with a clean install of Mac OS Big Sur.
I actually don’t have this problem anymore with Blender 3.1 alpha on Catalina.
(Still a few crashes, but no corrupt files. And crashes have to be expected with an alpha version.)
On Mojave I still have the corruption issue!
