Describe the bug Some crashes happened by accident when I was testing in different devices. I tried to reproduce them and found that they can't be reproduced, but they are real. I hope they can help you to debug.

Setup:

• Android version: [e.g. 7 or 10, etc] 7.0
• Is Your device rooted? No
• Do You use Tor or any VPN service with your device? No
• App source [e.g. FDroid, Downloaded from GitHub, self build] self build
• App Version [e.g. v2.977] v2.977

Thanks for the crash reports! I guess, a couple of the exceptions are not real crashes - for example when leakcanary complains about missing or empty files, but the others seems valid.
