P: Hang while using Shawdows/Highlights tool with the Histogram panel showing (macOS)

Especially not to re-inject parameters Workspace and Toolbar, it is necessary to recreate it !

Thanks.  I reverted to 21.0.3 and the bug is not there in that version.  I'll try the above suggestion later.  I have some work to finish first!  Lost a lot of time because of the crashes.

Do not recover the custom settings from the previous installation during the installation of this version and the bug will disappear!

I have the same shadow/highlight issue.  Mac OS X 10.15.3.  No Bitdefender. Uninstalled PS 21.1.0 and reinstalled, but it did not help. Adobe, this is a bug!  Please help.

Likewise here. This bug needs to be resolved quickly. Are you listening Adobe?

I can confirm that disabling GPU processing allows me to use the sliders on the S/H panel without the application freezing.  However, disabling GPU makes the app perform in a surprising way:  when first opened, 50mb DNGs do not display promptly.  Sometimes the image is only partly visible and partly gray, sometimes the image appears as a gray rectangle.

That also disable the rotate view tool, something I use all the time. The problem will be cleared when Adobe fixes the bug, disabling functionality of the program is not clearing up the problem.

I have the same problem, with no anti-virus software installed. Judging from the comments here, it's time to roll-back to an earlier version. I use S/H all the time.

Photoshop freezes when I use the Shadow/Highlights filter. I'm using Mac OSX 10.15.3 and Photoshop 21.1.0, but before updating to the new Photoshop version this error did not occur.
