Can't connect to hidden wifi networks with RTL8852AE since kernel 6.2

[laupefr]

Hello,

I've just discovered a regression after updating my ubuntu 22.04 to kernel 6.2.0-26-generic.

Since then it's been impossible to connect to a wifi with a hidden SSID.

When I reboot to the previous kernel version (5.19.0-50-generic #50-Ubuntu SMP PREEMPT_DYNAMIC Mon Jul 10 18:24:29 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux) all is working fine.

My wifi card :
02:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8852AE 802.11ax PCIe Wireless Network Adapter

My router : Orange Livebox 5
Configured in Wifi 5 with hidden network.

Could you have a look ?

Thanks for your help.

Connection to Wifi hidden networks also works very well with the LTS kernel:

5.15.0-78-generic #85-Ubuntu SMP Fri Jul 7 15:25:09 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux

I also just tested with Ubuntu 23.04 live ISO
Kernel version : 6.2.0-20-generic #20-Ubuntu SMP PREEMPT_DYNAMIC Thu Apr 6 07:48:48 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux

Connection to Wifi hidden networks does not work.
