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): Making sure you're not a bot!
