Error pop-up without using app

[Newar417]

Today I had an error message pop-up, even though I have not used the app in a good while. This is on a stock Motorola G4plus (Android 7). All the latest versions, Syncthing Lite is from FDroid.

This is the error as reported from the app error reporter function:
