The last thing PMS appears to be doing before the crash uploader runs is initializing hardware transcoding (using Intel Quick Sync Video). There were some known Intel driver compatibility issues several months ago which could cause PMS to crash when attempting to use hardware transcoding with QSV. There’s some additional information in this thread:
In the meantime, you could try disabling hardware accelerated transcoding on your system to see if that is indeed the issue; the thread above has a table of known “crashing”/“non-crashing” driver versions you could test as well.
It working with the desktop client makes sense, as it would likely not need to be transcoded when using it.
