Re: 'Failed to Launch Game: An Error on Our End' for Multiple Games. Any Fixes?

Here is my DXDiagnostic file, as it looks like that sometimes helps pinpoint the problem.

An IT friend suggested I check my "Controlled folder access" and sure enough, my laptop was blocking the sims 4 from accessing my documents folder... and, now I have allowed it through and the problem is solved!

Search for your "controlled folder access" and turn it off!! It's in Windows Security under Ransomware protection. This is the only thing that worked for me after hours of trying everything! 

This is the same thing for me. As soon as I did the update it can no longer launch. My "controlled folder access" is off - that has no effect. I cannot launch in offline mode either. Updated all my drivers, my OS etc. Cleared EA Cache. Repaired Game. Nothing. I see this was an issue a few years ago so what's the current resolution? I tried the old instructions and that did not work either. 

Hi, m8. After few days of battling this problem, I finally managed to get Battlefield 2042 to launch properly by following Steeve_BF second solution... Which is to perform a clean installation of an older Nvidia Game Ready Driver 577.0... (If you have an Nvidia Graphics Card) So, to anyone facing a similar issue with Battlefield 2042 for example, I strongly recommend that you give this a go... NVIDIA PLEASE... ;'( XD

I FIXED IT!!

I had this same issue happen today. My sims was working fine UNTIL I exited the app to download more custom content/mods, and went back to open sims and it said "failed to launch game". 

I am unsure if this would work for you, but here is how I fixed it.

You have mods that won't let Sims 4 launch. Maybe the mod/mods are incompatible with the newest Sims 4 update, I'm not sure, but you have to go through and sort out your mods to see which one is making your game break. For me, it was easy because I just removed all the mods that I had recently downloaded today (since my game was working fine before I downloaded them). I put all of those mods in a separate folder on my desktop, and launched Sims, and it FINALLY opened.

After knowing that one or multiple of those new mods caused my game to not work, I went back to check one by one to see which were breaking my game. Then I moved the mods that did not break my game back into my mods folder.

If you use mods, please try this, as it may fix this issue!
