CREATING PROXY JOBS takes forever

Although I’ve been using Adobe Premiere for years, I believe this is my first time creating an account on the community forum.
I’m reaching out regarding a terrible issue that Adobe hasn’t resolved, and it’s driving me insane day after day.

It has become almost impossible to edit files from my Sony A7III camera (4K 4:2:2 10-bit) unless I create proxies.
Alright, I’ve accepted the fact that for every bigger project I’ll need to generate proxies in order to edit smoothly.

However, “CREATING PROXY JOBS” takes at least 10× longer than actually creating the proxies themselves.
And this is driving me CRAZY!
This was NOT a problem before!

Some people on the forums say that Media Encoder scans all files in the folder and that it depends on the number of files — but I call that nonsense.
I tested this with a folder containing only 10 short clips and the result is exactly the same.

IS ADOBE PLANNING TO FIX THIS OR SHOULD I CANCEL MY SUBSCRIPTION???
