Do you know what numerical values mean? Test FurMark 800x600 without AA with the settings in this link. Finish the life of the graphics card in half an hour.
I wrote before the problem of your system to you that PSU. When the PSU capacity or the quality is low, it cannot adjust the voltage properly. Either it crashes when the PSU high loads. Or, the GPU crashes as it goes up to higher frequencies. The advice you give may damage the graphics card or the 550w PSU.
Edit:
pnputil /add-driver "<<RADEON-INF-PATH>>\<<RADEON-INF-FILE>>.inf"
For example: With pnputil command without /install option can be used. With this example command, Radeon driver is installed on the system without starting. It can be tried, I think. The other commands have similar installing features.
Note: Command Prompt must be start as an administrator for the all commands.
A PSU calculator says that over 400 watts the system will consume power with full load.
People who follow what this website writes may have problems. Because only after I bought a good PSU with a difference of 100w, I experienced how the system gets less warm and gets stable.
TechPowerUp shared this information for Sapphire RX5600XT. Recommends 350w. A friend was using 150w TDP RX 480 with a 650w PSU. And when he increased the GPU power limit, the system crashed. Even 650w PSU was very limited for the 150w GPU. If you have a lot of money and love the risks, you can see if it works by trying a low capacity PSU first. But I wouldn't recommend this to anyone. The vast majority of those who already share their problems either use an old PSU or use a low capacity PSU. I spent hours and money to keep the 9000 series Bulldozer and HD 7800 series GPU stable.
The website shared power consumptions about R7 5700 GPUs. What is R7 5700? Is there such a GPU? I do not know this. Also, the website does not contain information about 5600 XT.

I have already mentioned what I think but it may be useful to look at the documents. Even if the PSU is not enough, you should be installing the driver without problems. Trying the GPU with another system will allow you to have more ideas. You have to try different things. Not with one thing, or with me or with someone else's saying. I'm done for this topic.

Please try this method.
Access violation errors (Exception code: 0xc0000005) can happen because of different reasons. Corrupted files being one of them. I was getting this error daily. After doing a fresh install of the drivers (DDU and factory reset), I'm currently testing whether or not giving RadeonSoftware.exe admin access will resolve it if it is indeed running into access issues.
I'm on day 3 with no black screen yet. At this point I'd do anything to resolve it. I also gave full access in the security tab and disabled windows "full screen optimizations". I have no idea whether this will work or not but it can't hurt. I'll do what I can until AMD finally fixes this issue.
