Sorry, but you're both not giving enough information to actually being to think starting to investigate what might be up -- and you're using a distribution method we don't support, flatpak. This is something you need to figure out yourself. It is, obviously, not a bug in Krita's codebase, but a local issue. Please check https://docs.krita.org/en/untranslatable_pages/reporting_bugs.html to learn how to report bugs.
Thanks for the quick reply and I am sorry for my invalid bug report. I removed the flathub version and installed the ppa version of Krita via the krita website which solved the issue. Not sure what went wrong but indeed for sure then not a bug in the Krita codebase.
