broken compatibility with network manager 1.50

[Pradip-AGI]

Describe the bug
I recently updated my Arch Linux system to the latest version, which includes NetworkManager version 1.50. After the update, I am unable to use create_ap to create a Wi-Fi hotspot if my wireless card is already connected to a Wi-Fi network. The create_ap command only works if I disconnect from Wi-Fi first, but then I cannot reconnect to the Wi-Fi afterward. Essentially, this means I can no longer share an internet connection through the Wi-Fi interface while connected to a Wi-Fi network, which worked without issues before the update.

To Reproduce
Steps to reproduce the issue:

Update to the latest NetworkManager (1.50).
Connect to an existing Wi-Fi network.
Attempt to use create_ap to create a Wi-Fi hotspot while connected.
Notice that create_ap fails to create the hotspot on all channels.
Expected behavior
Previously, create_ap allowed me to share my internet connection through a Wi-Fi hotspot while remaining connected to the Wi-Fi network. After the update, this no longer works, and create_ap consistently fails to create the hotspot if the Wi-Fi interface is already in use.

Desktop (please complete the following information):

OS: Arch Linux 2024.10.01
Kernel: 6.10.10
Additional Information
This issue did not occur before updating to the latest version of NetworkManager (1.50) and kernel version 6.10.10. It seems the update may have introduced some changes affecting Wi-Fi interface management.
