HP Envy x360 standby not working anymore on 5.16.2-1

Hi Guys, i am using an Hp envy x360 (HP ENVY x360 Convertible 13-ay0xxx CPU: AMD Ryzen 4500U GPU: amdgpu). After upgrading to 5.16.2-1 my Laptop freezes after resuming from Standby. I have downgraded to 5.15.16-1 which fixed the problem. I have no idea how to file a bug report for it, so that this problem can be fixed in the next version of the kernel.
Any help would be appreciated.
