Desktop app won’t open since 1.6.16

Hello,

since version 1.6.16 the App won’t open.
I can only see the app in the task manager but nothing else appears.
Version 1.6.15 still works fine.
Does anybody had the same problem and solved it?

Does an update to Version 1.7 solve the issue?

I tried every version but nothing works.

Anything suspicious in the log file? any WARN or ERROR messages?

14:30:24.018 [main] WARN o.c.c.settings.SettingsJsonAdapter - Unsupported vault setting found in JSON: preferredGvfsScheme

This is the only Warn message.
