WiFi doesn't work on Manjaro (r8822be), but works perfectly on WIndows

I have a fresh install of Manjaro on my Lenovo Legion. The first time, WiFi worked and the detected networks were listed, but after connecting, it stopped working in sometime. Ever since then, it shows that no wireless networks are available, only the wired connection works.

Hardware:

07:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8822BE 802.11a/b/g/n/ac WiFi adapter (rev ff)
        Kernel driver in use: rtw_8822be
        Kernel modules: rtw88_8822be
08:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 15)
        Subsystem: Lenovo Device 38c2
        Kernel driver in use: r8169
        Kernel modules: r8169

Kernel: 5.8.18 (changing it to the LTS - 5.4.74 also doesn’t work)

Dmesg output:

Also, setting ‘options r8822be aspm=0’ and ‘options ideapad_laptop override_has_hw_rfkill_switch=0’ didn’t work.

Please help!

Hey, have you tried the AUR package rtw88-dkms-git? AUR (en) - rtw88-dkms-git

Thank you for replying!
I tried that, but the issue still persists.
One thing I’ve noticed is that, if I back to windows and come back to Manjaro with power supply, then wifi works!
