Omnisharp update v1.23.3 breaks references to common unity namespaces

I noticed after updating to omnisharp that one of my plugin namespaces wasn't being recognized anymore. Then when I brought up omnisharp in the panel I noticed a whopping 5k errors. This happened immediately after updating to omnisharp v1.23.3. Anyone know how to roll back to 1.23.2?

I've tried everything mentioned here:

EDIT: looks like its already been reported:

I found that rolling back to 1.23.2 does fix the issue for the time being


Oh wow... just spent the last 3 hours tearing up my dev env only to stumble upon this thread...

1.23.2 rollback...priceless.


Same issue here, some projects are broken while others remain untouched.

Got this nasty error and spent a whole afternoon trying to fix it. Somehow setting Unity's 'External Script Editor' option to Visual Studio 2019 fixed the problem for me.

Waiting for the fix. I really don't want to accidentally open Visual Studio when I debug and have the computer freeze for a good minute.
