Utkarsh,

Although James top posting made it difficult to send this properly, he is 
correct to suggest using the rtw88 repo at GitHub.com. It contains code that 
will not be in released kernels until v6.5.

Most systems handle suspend or hibernation correctly, there are some that do 
not. To my knowledge, all of these have been recent HP or Lenovo laptops where 
the BIOS does not handle D3HOT to D0 transitions.

If using rtw88 does not help your system, your best resolution is to install a 
script in /usr/lib/systemd/system-sleep/ that will unload the driver before 
sleep/hibernation, and restore it on resume. Repo rtw88 has scripts for all of 
the PCI drivers, and README.md tells you what to do.
