No issue here however, how big is your file

When error occurs Press OK, then a new tab opens with some text
Copy and post that text here

  1. See if any snack bar block is left without any input value

I do not have such blocks.
I solved the problem by putting firefox instead of chrome. Through firefox, files load normally.
