"There was a problem decoding some of the images..." Error message

Hello!

I was working in the animations editor when Construct crashed. Before the screen turned red it gave me this popup which I've never seen before:

After which I clicked OK and the red error screen showed up with this error report:

I'm not sure what It means but I was able to save the open project, restart Construct, and continue working on the project with no problems (so far!).

Any idea if this has anything to do with my system or is this an error on Construct's side?

Thanks!

Perhaps you tried to import a corrupt image. Construct shouldn't crash even if you do that though. It's hard to say any more without the same information a bug report requires (steps to reproduce, a sample file, etc).
