It crashes outside of digiKam. There are many entries from QWebEngine. Are you sure that your NVidia driver is still active after the update? The crashes indicate an active Nouveau graphics driver.

Please try with AppImage 6.2.0 pre-release compiled with QtWebKit if you use NOUVEAU driver for NVIDIA card. Bundle can be downloaded here ;
