Halo: MCC Update
Seems the recent update made the UI crash happen again. I was able to get it running by adding -windowed
to the steam launch properties. Switched the game to borderless in the video settings, and it ran fine.
Additionally, if you are trying to run it with a newer proton version and encountering difficulties, you may need to delete the prefix, which should be located in steamapps/compatdata/
. Find the folder with the ID 976730
, back up save data inside it if you wish, and then delete it. The next time you run the game, proton will automatically remake and configure the prefix.
Source.
Fingers crossed that 343 turns on the EAC switch soon.
