For reference purposes only, I will report here about the experience of similar problem with my laptop. My laptop also has the intel AX201 and
the dimidecode command shows as below,

Handle 0x0011, DMI type 1, 27 bytes
System Information
Manufacturer: HP
Product Name: HP EliteBook 830 G7 Notebook PC
Version:
Serial Number: XXXXXX
UUID: xxx-xxx-xxx-xxx
Wake-up Type: Power Switch
SKU Number: 20L69PA#ABJ
Family: 103C_5336AN HP EliteBook

I checked some kernel versions whether AX201 Bluetooth works or not.
As a result, my situation was a little different,
1. The AX201 works fine in Linux-5.14.16,Linux-5.15.5,Linux-5.16-rc2
and Linux-5.16-rc3.
2. It doesn't work in Linux-5.15.3 and Linux-5.16-rc1.
The Debian bug tracker reported a similar problem,
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1000403.
According to it, a commit between 5.15.3 and 5.15.4 can improve
this problem.
I'm not sure, but I guess the intel AX201 hardware has some versions,
and it causes whether the 5.15.5 and 5.16-rc3 works or not, for example.
