Serious issues with a 5080, asking for advice

Sorry to disappoint you but if you look in the details it's Chinese:
Amazon listing said:
The best DisplayPort cable KabelDirekt offer is DP 2.0 UHBR10.
It makes sense if you have a 4k@240Hz monitor and you want to max out its performance. Once you see that with games like Cyberpunk and MFG in action, you realize that you are playing another league.
In any case that deviates the focus from the main topic, which is the video output issue. I didn't expect that when I thought on the GPU replacement.

F@ck, you are right... and the ******** put German flags everywhere. At least I hope it's a German design, the little documentation coming in the package is in German and the contact information points there too. Things of the globalization I guess, these days you can also buy a pretended American Tesla that could be 100% made in China (lucky me, mine was made in Berlin xDD).
BTW the cable you posted is DP 2.0 and supports 4k@144Hz only. I guess that if the same brand advertises another cable featuring 4k@240Hz, it should reallly support a higher bandwidth.

Sounds like cable issues to me
Make sure with the LG OLED 32GS95UE-B you are using a good HDMI 2.1 cable (Fibre one)
Don’t use DP.
Also check the monitor is set to use DSC with HDMI.
Settings > General > Input Compatibility Version is set to 2.1(PC)

Thanks, you seem to know what you are talking about, regarding this monitor.
The Compatibility Version was already set to 2.1(PC) on HDMI, and is set by default to 1.4(DSC) on the DP.
This is the cable I was using:
https://www.amazon.es/gp/product/B08CRN8357
It's HDMI 2.1, has a bandwidth of 48 Gbps, and is apparently compatible with 4k@120Hz. Maybe I'm forcing it too much at 4k@240Hz, but then why the hell was it working fine with my old 4080??
The series RTX 5000 specifies the HDMI output in the version 2.1a. All the cables I found on Amazon in this version 2.1a claim to support 4k@120Hz only, and have the same 48 Gbps bandwidth (I actually can't find any other HDMI cable on Amazon with a higher bandwidth). I found others simply 2.1 that claim to support 4k@240Hz and seem to have a checkable certification from HDMI.org. Check this one:
https://www.amazon.es/Ubluker-Certificado-Oficialmente-10k60Hz-4k144Hz/dp/B08TGBLLXY
Do you think it worth giving it a try? Or do you think it's better to try one 2.1a even if they don't claim to be compatible with 4k@240Hz?
That's not a certified HDMI 2.1 cable, that's just labelled HDMI 2.1 but could be pretty much anything...
This one is certified, as you can see it has a certification tag and some have a QR code that can be scanned so you can view the certificate

It is weird that your current cable worked using your 4080.
I would try switching the input compatibility from 2.1(PC) to 2.1(AV) this will cause the monitor to go black for a few seconds and come back at 4K 120hz as DSC will be disabled.
I would then switch it back to 2.1(PC) and see if you are able to select 4K 240hz.
I would also check if you able to switch the monitor to 1080p 480hz and back and see if that does anything.
If they both fail to fix it, I would try a certified 2.1 cable that is under or 3 meters.
