Hi. I tried this on Arch Linux but also wasn’t able to reproduce it. You said that you are able to reproduce this easily, so can you share a few more details? For example:
layer type (vector/bitmap)
type of image (for example whether it is an animated image/GIF)
How you import the image (since Pencil2D offers several different ways to import images)
Any import options you specified (such as import position)
anything else you think might be relevant (in bug reports, too much information is always better than too little)
Ah, I think I understand now. It seems this crash occurs only when importing onto a frame without a pre-existing keyframe. Thanks for the video, that helped! Even if it’s not critical for you, this could potentially lose someone else a lot of work, so it’s good that you made this report. I’ll try to put together a fix for this soon.
