I had the exact same issue on FW13 ai 350 from new. After a couple of days running on older kernels that didn’t have that problem I found a solution on another thread in here that I don’t have bookmarked but what solved it for me was adding a parameter to grub config. Specifically amdgpu.dcdebugmask=0x10 to GRUB_CMDLINE_LINUX_DEFAULT.

Search for it and I am fairly confident you will find a solution.
