Premiere Elements 2023 on Mac Book Pro running M1 Max (24c) hardware accelerated export out of sync

Everytime I try to export a 4K 50fps Video using the hardware acceleration the exported video is out of sync. Audio is ok but the video is running like 30fps in time loop - audio and video is out of sync completly and the lengths of the video grow by 1/3.

Using the Software rendering the bug is fixed. strange. Mac Book Pro with M1 Max

Also the editor with hardware acceleration show the wrong video length but play audio and videoin sync.

Tried with different projects and Video sources - always reproducible. Anyone out there who has got the same problems / effects on a M1 Mac ? Looks like the codec parameters for rendering are not ok.
