Skyrim Special Edition does not launch with MO2

[Morogwen]

After install, I can hit Play. The game will attempt to launch and the Play button will change to the "Stop" button for a few seconds, but will switch back to "Play" after a few seconds. Running on Pop!_OS 22.04, RTX 3080 ti, Ryzen 9 3900X.

Might want to try validating your game files if you haven't already. That's a pretty decent catch-all for when it refuses to launch.

I uninstalled and reinstalled, following the instructions for MO2 each time, about 3 times now I think. I did have to get the latest SKSE from their website, which I've verified is up to date to work with the current version of SE/AE, so I'm wondering if there's a compatibility issue between this installer and the current version of SE/AE on steam, and if so are there linux noob friendly instructions on rolling back to a working version? (:

I have the same problem. After installing MO2 and click on Launch a small window opens and close immediately and my play button is green again.

Here is the console output:

I was able to take a screenshot of the error:

I initially had the same issue when I installed MO2 in the proposed directory. Reinstalling MO2 under the steamapps/common/ directory however solved the issue for me. I guess it could be a flatpak permissions issue, as I at least use the flatpak version of steam.
