XBox Series Controller starts to distory inputs after some time in wireless mode

I got myself an Xbox Series controller (Stormcloud vapor) in spring. I got it specifically for wireless. I know that 2.4 Wi-Fi distorts Bluetooth signal, so I turn wi-fi on my laptop completely. Despite that, after 10-40 minutes of normal gameplay with no issues, it starts to distort input: some buttons dont register, sticks and triggers either dont react or react for too long. Reconnecting right away doesnt work, have to wait like 30-60 minutes min. At my old home I used to hotspot 5g from my phone, that kinda worked, but now - I dont have such ability. I`m aware of dongle existence, but I dont think it will fix the problem. Controller firmware is updated, wired work is flawless, all the stuff with double inputs (like WindowsInput and Steam Input) was done. It does that all the time, only the time when it starts depends. I beg y`all to help, I am hopeless right now. Thanks!
