I'm having issues with my new PC where it shuts off unexpectedly when I start streaming or play Fortnite. I purchased it from DTX, and I think xtremepcgaming assembled it for me. I consulted some advice and downloaded a program to check my components and temperatures. It showed that my AMD Ryzen CPU is hitting around 80 to 90 degrees Celsius. I believe that's the cause of the problem. How can I resolve this overheating issue?

First off, it sounds like your CPU is definitely overheating. 90°C while gaming is pretty high, and it could cause your PC to shut down to prevent damage. Make sure to check your cooling system. If you have an air cooler, try removing it, cleaning it, and reapplying thermal paste. If you have an AIO cooler, check if the pump is working correctly; if it isn't, you might need to replace it.
It’s important to check what temperatures you're hitting when idle too, not just during gaming. Ideally, your CPU should be cooler when not under load. If you find high temps even while just using your PC normally, that points towards a cooling issue that needs fixing.
