It's a bug in kernel v5.15: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1970056
To solve this issue, upgrade your kernel version to v5.18 from mainline or look for tutorials online how to do that. Its really simple. Kernel v5.18 has no such problems.
However, it's not known how much time it will take to fix this in kernel version coming in ubuntu 22.04 which is v5.15
