AppData/Library/Caches/trn_thumb_cache breaks the app


Somehow we break something in our app. and when we try to open a any Document. the app stop responding.

I looked it up and found that when I delete the file inside the container /AppData/Library/Caches/trn_thumb_cache, app works again. I shared the file.

is there any idea what is the main cause of that problem, thanks and sorry for lack of information.
