EM120R randomly disappears on Linux

I have problem with Quectel EM120R on Lenovo T14 Gen 2i. Any significant network load causes a disconnect of the module

Distro: Arch Linux, kernel: 5.19.3-arch1-1
modemmanager: 1.18.10-2
firmware: EM120RGLAPR02A07M4G_18.018.18.018

I was redirected from (description of the problem): EM120R randomly disappears (#615) · Issues · Mobile broadband connectivity / ModemManager · GitLab

other: Quectel EM120 FCC locked (#402) · Issues · Mobile broadband connectivity / ModemManager · GitLab

is EM120RGLAPR02A07M4G_18.018.18.018 the latest firmware version?
