Seems to be working fully for me now, I tried a lot of different image and font files and it never crashed!

I was able to get it to crash by opening usually 4-5 external files. Fonts and images. Much better than it was before, but still a problem

Same, it seems fixed in 2.83, for both loading image textures and fonts!

I'm using Manjaro, and I recently started getting a buffer overflow when opening most image textures from the shader editor, and Blender crashes when I load fonts as well. The crash log doesn't seem to have any useful information.
