May I suggest the following ;
First thing is to synch cloud flights (little cloud icon) to make sure DJI servers are hosting all flights including recent ones.
Delete all GO apps (you might have the two installed.
Connect tablet to a PC and explore to delete all DJI folders in Android (or navigate in android within Storage in Tab settings).
Install last DJI Go app 4
You must have enough free disk space
Disabling video caching GO app option can help
If Tab goes very hot this may cause app to crash
Make sure there is no backgound task eating resources, Android might spend time doing other things for other apps or background services with impact on GO app.
Evidence, not same case but to show clean install ;
DJI GO 4 APP CRASH WHEN I OPEN DATA FLY
Edit: I have iOS actually and Mini 4 cellular (works great), so these are just based on earlier Android based posts and experiences I have seen, from memory.
Also you might want try with someone else device and compare. There is so many people having tablet or phone theses days even within same family. Good luck.
