KSPBurst Prevents Main Menu Load After Some Sort Of Freeze

[roryyamm]

I was playing RP-1 with a few non-Express Install mods. This worked fine, until I undocked from a space station. After this, the game hung for 30 minutes. I eventually killed the program.

After this, my game experienced a curious issue where it would load completely fine, but then never bring up the main menu screen. The game log, Player log, and even Strace confirm that KSP loads everything correctly, and then simply stops doing anything at all.

In an attempt to diagnose the problem, I tried to uninstall everything mod-related, save for a pair of config files that required mods to be applied anyway. However, this still caused the game to hang after loading everything correctly.

This has happened to me several times before, and my best option to fix the game was to reinstall everything, including the game itself. However, this time I tried to be more surgical. A delete-and-reverify strategy found that the executable, stock GameData folders, and KSP_Data were fine. What fixed the game was going into PluginData and deleting the KSPBurst@1.5.5.2-com.unity.burst!@1.5.5 folder. After this, the game loaded fine without mods and after installing the Express install.

Something is wrong with the Burst compiler. I was told to make an issue here.
