I checked the my picture directory and deleted a recently downloaded image., but didn't see any improvement. As I try to open the files I can see the download file, documents file, picture file etc. but no file appears (only in dutch) almost ready / maybe almost done. Lately I downloaded Libreoffice 7.3.03 wich I deleted and also deleted the paint.net prog. several times and re-installed it but nothing seems to help yet. If anyone has a solution I would be grateful.

Cannot open files in paint.net 4.3.7 also not with ctrl+o => files do not show and system gets stuck.what can I do . My OS is Win 10 pro 21H1. What can I do to solve problem, Thanks
