The logs say that you tried to load a savegame that didn't have metadata. Could it be that you updated to alpha 21 and tried to load a savegame from alpha 20?

[frapstar]

No. I install the Game 30 minutes before. A clean install of Alpha 21 Ulysses, no update. And i start a new Game, because there were no savegame, because i install it new on the Computer. The PC has 2 Monitors and the crash was when i switch (alt + tab) to the desktop. when i want to switch back into the game, there was this error.

[elexis]

Well in that case I reopen it. Perhaps the issue is reproducible when switching with alt+tab on dual monitors on other machines as well. Wouldn't be surprised if dual monitor support has some bug, perhaps windowed mode is more stable.

The savegame error still seems unrelated - sounds like a missing check for players without savegames.

I try in windows mode = Same error. It crash when i switch do desktop and back in the game. So yes the error is reproducible. I dont have this error at my other pc with only one monitor.

Alt tab has always been buggy on windows.

In 18997:

Save and load dialog bugfix. Reported by frapstar, refs #4361.

Change a wrong check in the save and load screen that didn't handle the "No saved games found" case.

I had a look today and here is the stack trace Maybe that can help someone to debug it.
