I just installed Lightroom classic on my new computer running Win 11. When I went to open LR, I got a popup which said, "assertion error". What is an assertion error? LR doesn't respond or come up like it should. What is happening?
I am having a same error last time. This error can be caused when the Pictures folder is no longer under your user account folder. It can also occur when the Windows registry no longer points to the appropriate Pictures folder.
