What theme are you using? For the above test I used the default 
mythcenter wide theme, Then I tried installing steppes. With steppes, 
mythfrontend crashes immediately after displaying the main menu, before 
I have a chance to do anything. The error is

03-13 19:35:54.170  8169  8246 I scudo   : Scudo ERROR: invalid chunk 
state when deallocating address 0x45409410
03-13 19:35:54.268  8169  8200 E mfe     : 
signalhandling.cpp:297:handleSignal  Received Aborted: Code -1, PID 
8169, UID 10115, Value 0x00000000

Scudo is part of android 11 and does memory checking.

So there seem to be other problems also.
