Can't do anything on canvas - not frozen as can change click other icons

Couple things to try:

If the canvas is dead as soon as you open a file, try this:

Go to preferences > Technology Previews... and check "Disable Native Canvas" - then restart Photoshop. Does the problem still occur?

If the canvas freezes when you pan or zoom after opening a file, try this:

Go to Preferences > Tools... and uncheck "Enable Flick Panning"

Hi try to reset your preferences or turn off canas option and make simple canvas or post a screenrecord so we can check what is real scene...regards
