Still no picture/ video in program monitor v. 25.2 build 15

Premiere Pro Beta 25.2.0 b.15

No picture on in-app monitors or external monitors via Mercury

Neither on nVidia or AMD or BlackMagic GFX or on Xeon or Ryzen 9 CPUs

It's a beta, I know, but three relealeses with same bug?

Why breake it if it works?
