It appears that its not just the pan (spacebar) that doesn't work - its several keys - all related to the lasso tool once the lasso has begun. Enter won't close a loop, spacebar won't pan, backspace won't go a step backward. Seems like keyboard input is ignored other than the escape key (so far that I have noticed). Issue happens regularly, ~10-20% of loops. This is highly aggravating when editing a large volume of images.
Based on similar threads the only fixes are ones that are registry hacks which disable pressure levels. Pressure levels are needed to be kept in tact.
Have already reset preferences and updated the software to the latest version with no luck. Wacom tablet driver is the latest version which supports Windows 11. OS is Windows 11.
