You're a genius. I did what you said :
"
activate the navigator panel, so the thumbnail is visible select erase brush in the brush panel, select the basic round brush, of size 64px click the “more” button in the toolbar, inspect shape of brush Try again to erase something from the pixel layer " And the rubber reappeared, thank you soooooo much!

Can you try to
activate the navigator panel, so the thumbnail is visible select erase brush in the brush panel, select the basic round brush, of size 64px click the “more” button in the toolbar, inspect shape of brush Try again to erase something from the pixel layer Inspect the Navigator thumbnail if erase effect if visible. Change zoom level a bit and check canvas again if erase effect if visible. The mouse arrow changes it size in the video. Do you have any 3rd party software installed, or activated accessibility tools like loupe, zoom? Any special input device (mouse, touchpad, …)?
