Shit’s broke yo.

Sleep/wake issues with AMD gpu and platform drivers are super, super, super common. Fish back through your kernel journal after a reboot (journalctl -kb -1 should do it) and look for the driver errors immediately after the wake event. If this has been fixed in a later kernel release then update your kernel, if not go report it to either the Ubuntu folks or on the amdgpu gitlab.
