Media Encoder just stops encoding proxies (only proxies!)

[Tolosuka]

Whenever I try to create a proxy, ME starts working and then just stops after a while. No crashes, no freezes - it just stops doing anything. I can hear my CPU vent slowing down and the CPU usage goes down to 0%. ME doesn't crash, it's still functioning and I can pause the encode.

The really weird thing about this is that this only happens when I try to encode proxies. Now I only recently learned about proxies and I never used them before so I don't now whether this is a new issue. Maybe it never worked on my system. Encoding videos (normal export) still works finde. It's just the proxies that don't work.

Was there ever a solution to this? I have also never used proxies before and just had this issue trying to create a proxy for an EOS R5 file that took 11 hours and has just frozen with 13 seconds to go when I checked in the morning! I wondered if it might have frozen because it's taking a while to write the file out, but the file size of the proxy isn't working. It looks like handbrake might be the workaround - but is there no fix since a couple of years ago?

+ 1 for this issue. AME seems to hang at the end of files and never finishes the encode.
