Verify that your memory is on the QVL list for your motherboard. If not verify that your motherboard is setting the correct timings. If you are unsure contact your memory maker and ask them what timings you should use. Running 3600 can be pretty tricky. You might try lowering that speed a bit just to test if that is contributing to the issue or not.
You can also run one stick at a time to make sure you don't potentially have a bad stick of ram. Unlikely but it happens.
I know you said you updated everything but please double check this:
Verify that you have the latest bios update for your motherboard.
Install the latest AMD Chipset driver. https://www.amd.com/en/support/chipsets/amd-socket-am4/x570
Disable Windows 10 Fast Startup. You can google how.
Even if you already loaded the latest driver please do this DDU setup after disabling Fast Startup.
Now get a clean slate for the graphics driver.
Run DDU from wagnardsoft dot com. Follow the included instructions.
Install the latest GPU driver Adrenalin 2020 Edition 20.4.2 Optional: https://www.amd.com/en/support/graphics/amd-radeon-5600-series/amd-radeon-rx-5600-series/amd-radeon-...
If that does not help I would talk to AMD support: https://www.amd.com/en/support/contact-email-form
