Joplin locked up. I think this was the first time in many years. I closed it. did a file exit. Re-opened and ok now. I think it might have to do with the outline panel as I had it open by accident. In any case, as I said, its not happened before or since and I use Joplin all the time.

However, the error message asked me to post the debug info to the forum or github. Here it is.

Error  
Joplin encountered a fatal error and could not continue.

To report the error, please copy the _entire content_ of this page and post it on Joplin forum or GitHub.

If the error persists you may try to restart in safe mode, which will temporarily disable all plugins.

Message  
Cannot read properties of undefined (reading 'removeEventListener')

Just in case it could be useful, I've been using it for hours every day for 9 days without any issue at all.
