I had the same issue with MacBookPro16,1 and fixed it by:

disabling ?dynamic? power management for AMDGPU (as it outlined here): echo high | sudo tee /sys/bus/pci/drivers/amdgpu/0000:03:00.0/power_dpm_force_performance_level
fixing this module which gets broken after the resume

UPD: Argh, no way. After the fix my mac does only one sleep/resume cycle well. The next attempt to sleep/resume results in rebooting the OS 😞

UPD2: Ha. After resuming power_dpm_force_performance_level resets to auto. So, making it high helps.
