So there is a problem with DDC and the EDID is not transported or faulty.

So what a coincidence: You can assume that probably not a pin of the HDMI input of the projector gave up the same time I firstly connected my new PC.
I can only assume that there was a kind of hardware conflict / bad implementation of the EDID transport.

It seems like the HDMI output of my new PC 'destroyed' / damaged the chip dealing with EDID in my projector - or do you have a better theory?

The HDMI output shouldn't be able to corrupt the EDID. Did you unplug the projector's power or move it at any point? Maybe it was already corrupted for a while and cached in the projector's memory.

Are you able to read the EDID with EDWriter? If it's corrupted, it will offer to fix the data. Then you can try writing the EDID and hope it's not write protected:

I am not 100% sure if the picture is the same like before.

How is the situation handled now? Is this connection now treated as DVI like the naming in Radeon settings (kind of fallback?)
The settings for pixel format disappeared, so what 'pixel format' is used with DVI, is it RGB Full (the one I want)? Is there anything in CRU where I can make a setting regarding that?

DVI is always full range RGB. To get an HDMI signal, add a CTA-861 extension block and an HDMI data block.
