File Manager disconnected, Apps don't work.

[Mohammad Sayed]

Hello,
I am using MIUI 12 eu based on android 11, file manager suddenly stopped working, whenever I open it immediately closes itself and says "file manager disconnected", I also recieve a notification says that my SD Card has a problem.
Apps close after few seconds of opening it.
My device is rooted with latest Magisk version, I tried many times to reboot it and cleared caches and dalvik but no solution.

Problem solved.
Go to apps > dual apps > settings icon on top right > delete dual apps accounts and data (device will reboot automatically)
