Ubuntu 22.04.3 LTS wifi not working

Initially, when I installed Ubuntu on my HP Pavilion x360 for 2-3 hrs everything worked fine but now suddenly my wifi is not working.

Kernel version: 6.5

Network card: Realtek 8822be

Ubuntu version: 22.04.3 LTS

when i use lshw -class networkthis is the output

Before I also tried Linux Mint same issue was there.

Update: when I restart my laptop wifi connects for 1 min then disconnect again

The error it was showing is:

Activation of network connection failed
