Hello there, i've been seeing a lot of other people having this issue aswell but figured id post here just to see what people have found as of now.
I was able to play just last week on my old computer, as i recently got a new rig i figured i'd download BF 2042 to try and progress with the cosmetics and such for BF6 as im sure other folks are doing aswell. Unfortunately im completely unable to get into either BF 2042 or BF1, every time i try to launch either game it pops up on the EA App with the same error "Failed to launch game, An error on our end caused the launcher to fail. Try again a little later."
This has been an ongoing issue for me since last Friday, but i've seen posts going back a few months with people having similar issues.
I've tried essentially everything besides reinstalling my BIOS and reinstalling Windows, which i honestly think is a little much just to be able to play a select few games as im not willing to potentially screw with anything related to either my BIOS or Windows.
That being said, i hope someone here has something i've not yet tried.
Just to add, I tried launching BF 2042 through both steam and the EA App and i tried launching BF1 just through the EA app because i bought BF1 on Origin when that was still a thing. Doubt this info is of any importance but figured i'd put it here just in case. I am also not using any of the mentioned preview / insider versions or updates of windows as mentioned in the comments of a post from another user.
