Android game does not load fully sometimes

I have a android game. I’ve developing it for year. Recently i started the game і after the unity logo nothing happened then I restarted the game about 5 times and it started. This happens once a day. I did not do some new features on last updates, did not change the Unity version for all time, i have enough RAM on my phone, no errors in Console(I used development build for find the problem). This bug appeared for no reason i think so.
Please help me
Game posted on Play Store for 4 months and with this bug all of current users can not playing and so deleted the game((((
Thanks

You have to remote-debug to find out.
