PL 7.3 crash after update from 7.1, Win11

I have installed the update from 7.1 (which ran without errors) to 7.2 and 7.3. In both cases, Photolab 7 crashed immediately after starting (with the corresponding option to send the error report). In my opinion, the cause can be found in the settings of the user.config file. There, under , the folder was saved in which the last browsing was done before version 7.1 was closed. In my case, a network folder on the NAS. I then adjusted the settings in the user.config file so that it points to a local folder on an internal hard drive/SSD. 7.3 then started without any problems, even though a network folder is now saved there again as the last navigated folder.
