Mcm Client App Crashes. Right click on mount & blade ii: Check run this program as an administrator and click ok.
That is what force stop is for, it basically kills off the linux process for the app and cleans up the mess! It crashes within half a second after pressing play game. From there clear data & cache.
I have a new s21+ coming from samsung thanks to sprint.
After swiping on the mcm client notification and clicking the gear icon to get to notification settings, tap the yellow mcm client icon to access the app settings. I have the exact same problem on exactly the same device. I have 2x4k monitors hooked up, running on 3840x2160. Content settings to set unique app behaviors.
