SLOW Lightroom and non-functional Photoshop after most recent CC update

I undid the System Restore and applied the newest update for Photoshop (which was not there yesterday).  That solved the issue!  I can open NEF files from Lightroom into Photoshop and apply layer masks, use Liquify, etc as usual.  It looks like I now have 2 versions.

Thank you, everyone, for your replies and insight.  In my frustration in needing to have a functional Photoshop, I used Windows System Restore.  Now Lightroom won't work (load) at all.  I will uninstall it and reinstall it later today.

luzye_photo  wrote Lightroom is very, very slow to being with.

I have several computers. My computer at work configured by IT is super slow on everything. May computers at home, nominally weaker, are fast enough -- I would not say lightning fast with Lightroom, that would be a lie, but fast enough for working with.

Now as to your much worse issue, performance.

First many members will request you accomplish the following as a baseline. Note that this is a tried and true procedure that eliminates arguments.

In LR, click on Help, click on System Information, click on Copy. Paste results in a reply.

Now as to your issue with Photoshop not working correctly when sent image(s) from Lightroom Classic Cc.

This is a known problem with the latest Photoshop update, Hopefully it might get fixed in the next update. None of the members of this Forum know.

It is now seen as a very old issue, repeatedly brought up in this forum. I will count to ten, Ok.

Three workarounds, I will list them from probably most tolerable (note I did not say acceptable, or desirable),

1. In PS, in preferences, disable the home screen

or

2. Start PS before sending it image(s) from LR

or

3. Degrade PS back one version.

I reached out to other photographers, and yes, they are reporting similar issues.  Is Adobe aware of the problem with the latest update?
