Adobe Media Encoder not Working with Premiere Pro Beta

[Peter_McC]

As of yesterday Premiere isn't starting or passing information to Adobe Media Encoder Beta. 

I'm using Premiere Pro Beta 25.4 build 47 and Adobe Media Encoder Beta 25.4 build 45. 

My PC is an Intel Core i7 265 with an RTX5070 on an Asus Z890 motherboard. All drivers are up to date. Windows 11 Pro 24H2.

I first noticed this when Ingest wasn't involing Media encoder and then today trying to export a video nothing happens when I Send to Media Encoder. I have tried various export presets including both h.264 and h.265. Premiere Pro exports the video fine when I don't use Media Encoder. 

I have reset preferences on both Premiere and Media Encoder and then uninstalled both not retaining any settings. I reinstalled them through the Creative Cloud Desktop but the problem is still there. 

I can't think of anything more to fix or diagnose.

I have tried this on another PC running same versions of windows, Premiere Pro Beta and Media Encoder Beta and it works properly. So it's clearly not a bug but having done a clean installation I don't know where to go with a fix. The only material difference between the systems that I can think of is that the one with the problem is running an Nvidia RTX-5070 and the one running properly is running an RTX-2080. Any suggestions will be appreciated.

I'm on 24.4 b48 with a just installed, clean Win 24H2 and it's working OK. I just selected all the defaults.
