[1.40.4] Softlock on refreshing while a (cached) custom map is selected (dev branch)

[TheBlackParrot]

Seems very random when the exception is thrown. Was able to trigger it with only SongCore installed.

Easy way to try triggering it:

• Launch the game as normal
• Go to the Solo map select screen
• Select "All Songs" in the icon tabs
• Select any custom map
• Press R to do a quick refresh, and (occasionally?) see the thrown exception. The game is now softlocked, as the back button no longer functions.

Didn't realize until after making this issue that the map has to be a cached map (from a .zip file), my bad.

I don't think this has anything to do with cached maps. I don't know how it could. This issue is already fixed locally since it was already reported to me on Discord.
