Steps to reproduce the issue

1. Updated Joomla to version 3.10 which worked fine
2. followed the steps here:
   https://www.joomla.org/announcements/release-news/5837-joomla-4-rc-1-and-joomla-3-10-alpha-6.html
3. Produced an error and didn't let me log in to front or back end:

"500 Whoops, looks like something went wrong.".
Something is broken. Please let us know what you were doing when this error occurred. We will fix it as soon as possible. Sorry for any inconvenience caused.

Tried following the recommended steps to add the missing tables etc. Still didn't work.

Here is the stack trace report which hopefully means something to someone?:
