Upgraded from 1.0.231 I believe it was. I started the new version, 1.0.236 and after opening it asked to do the upgrade and restart. This was expected by the release notes. However, after sitting for a LONG time (we are over an hour now), it will not start. In the process monitor, I can see it running but with a sleeping status. I have approx 1000 notes.
I am using Ubuntu 18.04.5.
