Photoshop was opened from Lightroom Classic CC

If you quit Lightroom and Photoshop, then launch Photoshop first, does it work normally without error?

Apparently so. I've been doing that si ce it was proposed as a solution. Haven't tried since without PS launch first.

I just tried opening a couple times to open a file from within LR Classic CC 2019 directly to PS CC 2019. The helper application error did NOT occur. 

The only significant change that I recall making in the interim is that on 11/30/2018, I deleted (well, actually renamed) the Lightroom Classic_20171021 Previews.lrdata file and allowed it to rebuild the previews.

20.0.1x is a terrible release. They obviously did not QA the release. It's super buggy with a ton of issues. Support told me there is a new one being released soon to address the "known" issues.

OK. I suspect you're seeing this issue: https://feedback.photoshop.com/photoshop_family/topics/many-ps-20-0-1-functions-missing-on-image-ope...

We're investigating this issue. Looks like launching Photoshop first, then launching Lightroom will force this to work correctly.

Disabling the Home Screen also works (as long as you don't work in full screen modes).
