I'm sorry to disturb you, but I've had a very troubling problem. When I try to open the animation file that I have already finished with version 4.2.8 of Krita, the Win10 system terminates and the termination dialog box pops up. The dialog box shows: krita.exe has stopped working. Please wait while windows reports the problem to Microsoft.

Because I've drawn dozens of frames, I can't give up this file. I downloaded version 4.2.6 again and tried to open a file that version 4.2.8 could not open. I succeeded. After dozens of experiments, I found that on my computer, version 4.2.8 could not open any krita animation file, even if the file was only less than 10 frames and made by version 4.2.8 itself. When I use version 4.2.6 back, these animation files open again! I had to use version 4.2.6 when I couldn't solve the problem.

My questions are as follows：
1. Is the problem widespread? Is it only on my computer, or is it the same for all users？If it is the former, then how can I solve it？
2. Will the 4.3.0 version under development solve this problem？
3. Why is there no problem with version 4.2.6? Is there any negative optimization in version change?

Wish you good luck.

P.S.I submitted to the wrong partition just now, but I couldn't find the button to delete the post.

* Please report a bug on bugs.kde.org and attach the animation file so we can see what's up.
* Have you also tried 4.2.7? That would narrow down when the regression happened.
* As for 4.3: you can test nightly builds yourself (https://binary-factory.kde.org/job/Krit ... ows_Build/)
