Can you please download Krita Next from the website and see if you can reproduce the crash? If not, it's very likely it's a duplicate of bug 459510 and that commit (that reverts previous commit) just needs to be backported.

It wasn't backported because Lynx3d didn't find the offending commit on krita/5.1, because it has a wrong commit message.
Bad commit on master: https://invent.kde.org/graphics/krita/-/commit/9b7318c13298e2fc52b52ac0d760a62152d4a838
Bad commit on krita/5.1: https://invent.kde.org/graphics/krita/-/commit/f6389225
Unrelated commit with the same commit message: https://invent.kde.org/graphics/krita/-/commit/5b52e54952280f49d89476d2711a746005a67462

Commit that reverts the bad commit on master: https://invent.kde.org/graphics/krita/-/commit/eda2d6fbc2ad4949ee96c4ab3f6f10d39a1b422c
And there is no commit that reverts it on krita/5.1 .
Comment 2 Tiar 2022-11-05 03:10:44 UTC
Git commit a943b8c708f8a1c921940aea42829c94476f1cbd by Agata Cacko, on behalf of Mathias Wein.
Committed on 05/11/2022 at 03:07.
Pushed by tymond into branch 'krita/5.1'.

Revert "Make sure that thumbnails are generated from exactBounds()"

This reverts commit 9b7318c13298e2fc52b52ac0d760a62152d4a838.
(Note: commit 9b7318c13298e2f is the commit from master.
On krita/5.1, it reverts commit f6389225, which has an incorrect
commit message but is the same commit as the one mentioned).

Hello, Tiar!
Yes, `krita-5.2.0-prealpha-c64143d85e-x86_64.appimage` from nightly builds has it fixed.
