SUMMARY There seems to be issues for Krita 6 where incremental and backup saves do not work properly. I've tried 5.3.0 and saving using those options work on that version on the same machines. STEPS TO REPRODUCE Attempt to save using incremental version or incremental backup. OBSERVED RESULT 1. Save document normally (ctrl+s), no issues, though the usual backup (~) copy does not get created. 2. Save document using incremental version, get error popup: "Krita alternative names exhausted try saving manually with a higher number" 3. Save document using incremental backup, Krita locks up completely. EXPECTED RESULT Backups are made and saved.

Could you please check whether this also happens with the appimage?
I can reproduce the issues with incremental save and incremental backup on Krita 6.0.0 (on macOS). Incremental backup gets stuck here: > 0 QtCore5Compat 0x10622d4a0 invalidateEngine(QRegExpPrivate*) + 56 > 1 QtCore5Compat 0x10622e3d4 QRegExp::replaceIn(QString const&, QString const&) const + 168 > 2 libkritaui.21.0.0.dylib 0x105354854 KisViewManager::slotSaveIncrementalBackup() + 14760 There must be a mistake somewhere in the if-def'd code for the rewritten regular expression handling on Qt6. However, I don't have any issues with the normal ~ backup.
