Your PNG has some data (I have not been into a deep analysis) that fails the analysis as an APNG (animated). Although it was properly loading.
I've added an exception handling to fall back into handling it as a standard png.
I works with the image you've sent. Can you do a deeper test ?

crash.txt

hello! It still Seems 2 crash, even with the Zip you sent me n on the latest Version. i'm Not too sure why..

Can you provide the new crash.txt for analysis ?

[pubpub-zz]

I'm confused the crash.txt you've sent look like my old one : can you delete the existing crash.txt file, and rerun the test.

I had a similar issue, but thought it was just me. The executable packed with 1.9.100 seemed to fail for me, while the earlier executable seemed to work fine. My initial 1.9.99 download didn’t have the executable packed with it; only the .bat file fix, which still seems to work.

Here's the error I get with the .100 bundled .exe. The older .exe runs opens without error, though it seems to have a new bug when switching back from clipart drawing back to pen. It seems to get stuck on clipart input even when pen is selected. Perhaps this might already be fixed, though, in the new .exe when it runs.

@sptssq, have you been able to reproduce and collect a fresh crash.txt ?

In your test you are still running / using the old version. Do not forget to exit / kill ppink.exe (using task manager) before starting the ppink from https://github.com/user-attachments/files/23028004/ppInk_png_failure.zip

The beta version is from 21st of october

I will reopen this issue until the fix released
