When launching the game, it crashes after a few seconds.

Unfortunately, I’m no longer able to attach the error log files for this issue, as I’ve already reinstalled the game and cleaned up all related folders afterward. However, I can report that a similar situation occurred to me one more time: during world loading, the game failed to load the world and crashed. What helped in that case was completely deleting the contents of the Temp folder located at:

C:\Users\User\AppData\Roaming\SpaceEngineers2\Temp

After removing all files from this folder, I was able to play normally again - the game successfully loaded my old world file. In total, this happened four times, and each time clearing the Temp folder resolved the issue.

I can also confirm that one of the causes (in one instance) was a corrupted blueprint uploaded to Steam. In that particular case, deleting files from the Temp folder didn’t help, what actually fixed the problem was removing the ship’s blueprint folder directly from the Blueprints directory at:

C:\Users\User\AppData\Roaming\SpaceEngineers2\AppData\Blueprints

If this issue occurs again, I will make sure to collect and send you the relevant log files immediately to assist with troubleshooting.
