When I click on Edit on Character Sheet, the sheet closes out

I don't know exactly why is happening, but I play and GM in a few different games and since today everytime I click Edit in a sheet, so I can change avatars and tokens, the sheet simply closes and do not allow me to Edit it. It's happening in all my games, in ALMOST all sheets, there is a few sheets I can still edit (mostly sheets that don't have any Avatar or Token), but most of the sheets simply closes.

Same here. I also cannot open some handouts... looking at other posts, it may be handouts with images attached.

I was going to make a post like this myself. Happened right in the middle of making preparations for a session later today. I hope the party doesn't have to fight anything...

Same occurring to my GM and I, just closes the sheet the second you hit Edit.
