GIMP crashes when opening png on mac

[blogsofwardotme]

Hi, I know opening png is an issue, but all the help is for windows. Anybody can open png on mac sonoma 14.7.6?
Here is all I have: my png is almost open, see the blue bar, and, as soon as I press Convert, it crashes. I also tried Keep, same thing.
Tried a million times so it was not an accident.
While I am here, what is the best size in pix to uplload a screenshot, I am down at 800 X 800 jpg and it's still telling me it's too large.
Thank you.

For JPEG and PNG the limit is 500K. PNG size depends heavily on contents (text, icons, CGI and flat areas compress very well), but if there is a significant amount of photo-style image the JPG is a better option. Note that we don't need you whole screen, your Gimp window(s) are enough.
