Media Encoder crushes on Windows 10. (XMP)

Hi there, Media Encoder on my Windows 10 PC is not working anymore. Every time I try to encode H 2.64 it get's stuck at 'reading xmp' and then eventually crashes without a specific error message. When I try to encode the same file on my Macbook Pro there's no problem with ot at all. My windows PC is much more powerful however, so I need it to work there again - as it used before! This problem suddenly occured out of nowhere. Any help is apprechieated...
