I upgraded my Macbook Pro to MacOS Big Sur yesterday and when I tried to Save For Web on my Photoshop CC 2019 it showed me this screen. I already tried reseting it to essentials but its still not working. Did this already happen to someone?
We're sorry about the trouble with Save For Web window in Photoshop on macOS Big Sur. The 2019 version you're using has not been tested on macOS Big Sur & there might be compatibility issues. Please update Photoshop to the latest version & let us know if the issue persists.
