I have installed your ROM, and I'm getting a constant popup that says "Game Launcher keeps stopping". Clearing the app data and force stopping it doesn't resolve this. Also, the Galaxy Store is missing, and when I download it from SamMobile it goes to the splash screen like it's going to open, and then it quits back to my home screen without an error message. My guess is that the Galaxy Store missing is why my Game Launcher isn't working. Because of that I also can't update any of the Galaxy Store apps (including Bixby to be able to change how the side keys work).
This was a clean install with a full wipe after installing on my N968U1 (Note 20 Ultra 5G).
EDIT: When I sideload the Galaxy Store app I can't open it directly, but I CAN go into Bixby which prompts me to update it, and then it will take me to the Bixby app in the Galaxy Store where I can update it. From there I can do a search for whatever app I need to update. But if I try going to the homepage of the Galaxy Store app it crashes with no error message. But at least this way I was able to update the Game Launcher, and that appears to have resolved the "Game Launcher keeps stopping" issue.
