No video - only audio after rendering

[danielg49372157]

Since today I have a problem with a certain media file coming from a DJI Mavic Air 2 (4k, HDR). As soon its rendered, video is no longer playing, audio is not affected. The very same project I could render yesterday without any problems isn't working anymore for this particular part coming from the source. Means that parts from other 4k sources are rendered correctly and video stops as soon as the DJI footage is reached. 

I am using the latest Premiere Pro version. No Windows updates inbetween.

What I tried so far (to no avail):

- only software rendering

- different frame rates (only with 25fps (source footage has 29.97) I could get some choppy output)

- speed = -100% (getting choppy output)

- same in all players from Premiere internally to different Windows players and iPad

- New project, new sequence

- Installed latest AMD Radeon Pro WX4100 driver

- different codecs

- no fx at all

- V1 activated/deactivated

- different resolutions

- deinstall -> install Premiere Pro

- restart PC

- clear all media cache files

- imported source from other location

- I played a lot with different settings for sequence and project

- probably even more... just don't remember

Source footage is working great on another PC here, same version of Windows and Premiere. 

Any advice? Thanks in advance!

Danielg ................ I can offer no advice other than to say, that since I updated to 14.4 I to can no longer access assets on my computer. I can hear the audio but not see any images. I have also posted on here tonight

Workaround:

At least I found a workaround: converting the H.265 footage to H.264 (e.g. using VLC player). Other footage shot with the same drone in H.264 works fine. 

Just want to know why Premiere Pro suddenly stopped to render H.265?!
