Hello!
Recently today I tried saving some work in progresses on the latest version that being 5.3.2.1.
I can name and save the file but when i go to look for it in my recent works it does not appear nor when i search it up. (I also use a Mac mini Catalina ver 10.15.8 with an Intel HD Graphics 4000 1536 MB) And still have plenty of memory.
I tried trouble shooting the issue by un-installing and re-downloading krita but that did not help.
