First off, you're running on the iGPU in the Ryzen CPU. The RTX 2060 is disabled. I assume that's a deliberate part of troubleshooting?
I know you've run Memtest but all of these latest dumps (from today and yesterday) point strongly at a RAM, or possibly CPU, issue. We're seeing an illegal instruction bugcheck, a LIST structure corruption, a memory access violation, a stack buffer overrun, and a misaligned instruction pointer. Many of the dumps were running graphics operations, but not all were, and they all fail for different reasons.
I think for now we should accept that you've tested the RAM and found nothing obvious, so we should next turn our attention to the CPU. I'm in agreement with @
zbook that running Prime95 is the best next step. I suggest you run all three Prime95 tests, because we don't just want to stress the CPU we want to stress the CPU and RAM interface. Run each test (small FFTs, large FFTs, and Blend) one after another for at least 1 hour per test, longer if you can.
This WILL cause your CPU to run hot, so also run a temperature monitor (such as
CoreTemp) to keep an eye on your CPU temperatures.
If Prime95 displays any errors, if the PC crashes or BSODs, or if the CPU temp rises over 100°C (Tmax on your CPU is 105°C) then stop Prime95 and let us know what happened.
