I hid Magisk Manager and forgot to un-hide it when I dirty flashed an update to my custom ROM. After dirty flashing the ROM, I installed Magisk again thru TWRP. When the phone booted up, I checked Magisk Manager and it displays "Magisk not installed" but there was a system message that shows "Magisk Manager has been denied superuser rights". I then realized that this was because of the hidden Magisk Manager that I forgot to un-hide.
I checked if I still have root and yes I still have it. I noticed that the "hidden" Magisk Manager still works when an app is asking for root.
My problem now is that I have two Magisk Manager installed. The hidden Magisk Manager doesn't show up in the app list but it still works in the background.
How can I uninstall the "not hidden" Magisk Manager and recover the hidden Magisk Manager that still works?
