Hey matiooo0,
If this is happening right as the match is trying to load, especially after the update, there are a few things to try and help get this cleared up.
If you haven't already, I'd definitely start with a repair on EA app, or Verifying Game Files on Steam. That will help make sure there weren't any corrupted game files during that update and everything patched correctly.
On a similar note, please be sure you've checked for the latest Windows + GPU updates. Especially with the screen just turning black and crashing, I'd check you're using the latest GPU drivers in particular. If you've already updated to the latest, it may help to use something like DDU for a clean install.
You can also try resetting your local config files by checking your Documents folder (not AppData) for EA SPORTS FC 26 and deleting the contents. That will reset your in-game settings to help avoid any potential issues. If you're using any overlays like Discord or Game Bar, I'd temporarily disable those as well.
If you're still seeing this happen after that point, please grab a Dxdiag and that will give us a bit more info as to what may be going on here, thanks!
