Since I upgraded my PC with Ryzen 5 5600 and RX7600, I have been getting green screen during POST, UEFI and during boot.
There are no such issue in Windows or Linux.
How do I solve the issue?
CSM is off in BIOS for Resizable BAR support.
P.S - BIOS was greyish black before this issue persisted.

Check your monitor cable or try a different monitor. Also, check in a different hdmi slot in the gpu. Nothing major but irritating.
Also, google for similar issues if people are facing around and do a bios update.
If it’s fine within windows, then your BIOS is corrupt. Reflash it
Updating the bios did not make any difference.
Will do that. Gpu has only 1 hdmi port. Will check with the cable.
I see a similar issue and probable fixes here:

Another crapyness of amd gpus..
I saw this before but I could not find the option since there is no Video section, but alas I fixed it.
Changed the colour to RGB (full) from YCbCr and it worked.
The option is under Gaming → Display ->Pixel Format.
That potential fix was also listed on the Reddit thread. Good that it worked in your case.
Hopefully anyone in future here who has this problem finds this thread and can fix the issue as well. Cheers! 
Just as I feared, the solution is not permanent and the reason I didn’t opted for this initially.
The problem is that the solution is Windows driven and only works when you apply and restart but once you shutdown the PC and come back after a hiatus the problem still persists.
There has to be a BIOS driven solution. This isn’t a permanent solution. Maybe, I’ll try remove the RAM and reinstall it in different slot.
Dark Star, did you resolve your issue? I’m having the same issue, sometimes it doesn’t happen but it’s still a problem. Also, my pc crashes after waking from sleep and whenever it wants to crash.

Post your details DDR5 info (model, specs, speed) maybe it’s just a matter of running the DDR5 at lower clocks.

I enabled EXPO I, high bandwidth support (or something like that), low latency in the BIOS.
The RAM sticks are running at 6000 MT/s. I noticed that Ryzen Master (the software) is showing that EXPO is off, although it’s enabled just as I said.
Thanks for your time.
Yes and no. If you are sticking to Windows the aforementioned solution does work but if you switch to Linux and then reboot the issue resurfaces. Since, the solution is implemented on Windows level and not on the BIOS, it will reappear if you switch to other OS.
As for the other issue, in my case, I did find the system to not wake up after sleep but it happens rarely. The system will wake up and fans works as expected but will not give any signal to the display. This is mostly true if I power off my monitor after putting the system to sleep/autosleep.
