I've got a problem on TM2020 and I don't know if it's the controller or not

[faint minnow]

Hello, I've recently started playing TM2020 and bought a controller because I don't really like it on keyboard. The thing is that when I play with my brand new controller (https://www.amazon.fr/dp/B0B3VNXZ8F?ref_=cm_sw_r_apan_dp_8QEH10YXCKA6SW3Y2S0E) it occasionally stops accelerating like this https://youtu.be/e9xF_NmimdY (sorry for the music) and I don't get why. It doesn't happen when I play on my keyboard so I'm a bit lost. Do you guys know this controller? and if so, do you know if it can cause trouble like this?

• I accelerate with "rt" and tried binding it on "a" but doesn't seem to change anything

do you by any chance have the steam controller support enabled?
