Media Encoder only renders 1 frame from Premiere Pro

I had this issue in previous version:
When I export from Premiere Pro to Media Encoder to render or if I try to create proxies, AME only renders 1 frame and all i get is a still image for the duration of the original video sequence...

I deactivated Dynamic Link which solved my problem...

Now after the last update I have the same issue, but not from the beginning:
Started to create 15 proxies in a queue... everything fine...
Then i startet another 4... fist was fine, 3 others again just 1 frame... all 4 was 1 queue!

I tried a proxy that already worked... it didn't work again.... doesn't matter what I want to render, I just get 1 or 2 frames an then just this one image for the duration of the video!

I tried to deactivate DynmicLink again ("native import") but for what ever reason it doesn't solve my problem anymore!

Can anyone help please? really urgent and I have no idea what to try...
If I render with Premiere Pro everything is fine, but AME just gives me a video with the correct length but all frames are just the first frame like a standstill!

And it stopped working in the middle of a queue which is extremely strange to me!
