I have checked out the log in my profile directory, here are some more clues:

2024-10-02 01:04:56: joplin.plugins: Finished running onStart handler: joplin.plugin.alondmnt.time-slip (Took 265ms)
It seems that my plugins are being initialised more than once?
Further down the log, Time Slip has some complaints:

Clearly there is something dodgy with my environment / set of plugins.
Thanks for your assistance with troubleshooting, I'll continue to look into this, however I'm leaning towards a new install and limiting my plugins (I have many installed and inactive, some installed that I don't really use, etc) as well as checking the logs to see where things are going wrong
