Pink screen flash when uploading photos on iMac after macOS Sonoma update

I just updated to Sonoma 14.7.6 (23H626) on a 14" iMac. I get the pink screen flash when I upload photos to a website. The upload is successful but obviously there's a problem. When I click on the icon below this page to upload I get the flash. A restart didn't help. Thanks.
