This seems to be related to bug 414672 and bug 415625, can you please download Krita Next appimage from the website and test it on transform tool to see if you get any crashes or assert messages in the console or if the tool behaves correctly?

After I sent the bug report, the error happened 5 times more, every time that I attempted the same action, which was in fact using the transform tools. so yes, it seems to be the same bug you identified.  I tried to reproduce the bug with appimage but I had already changed the situation that was causing the crash in the first place and I didn't get any more crashes using the transform tools far.it seems to be working correctly.
