Hello,

i'm pretty new to Xiaomi EU Rom and hope i'm doing right with reporting this bug :)

I'm using Nova Launcher and when i tap on the "Open Recent Apps" Button i just get a notification that System Launcher keeps on crashing, sometimes it opens but only shows a blank screen.

If im using the System Launcher as default Launcher the recent Apps function is working.

I think it has something to do with the Xiaomi EU Rom since this is happening since the latest weekly update.

If you need any further information just let me know.

If somebody knows what to do to fix this i would be very happy :)

Best Regards!

Hi,

it's a Xiaomi Mi 10.

Tried rebooting of course a multiple times. Also searched any Setting that comes with Xiaomi Rom and Nova couldn't fix the problem.

No problem. :)

Can you try to clear "All app data" of the "Miui Launcher" app in phone's settings and check if you can reproduce your issue?

;)

Hi… if it does not work, try this:

Start TWRP -> select Advanced -> choose File Manager and delete the folders if exist
  • /cache
  • /data/dalvik-cache
  • /data/system/package_cache
