Finder crashes when opening a file from app or copy file
Hello.
I'm experiencing an issue.
When I open a file from an app (such as Atom, or Gmail when I try to attach something, or Illustrator) or try to copy a file from a folder to another, the Finder crashes. I usually have to wait for about 15 minutes to defreeze; then it works as expected. Other times I try to force quit the Finder, but If I then try again, it crashes trying to perform the same operations.
I think that the problem showed up with Catalina (no minor version in specific).
I would try to fix it someway; I already try with Onyx, but no luck. Disk seems to be fine.
What else could I try?
Thanks to everyone.
