Same here.
Started playing the game on Cloud after getting Xbox’s Game Pass yesterday. Am on PC, playing on Chrome, and I was having a lot of fun, no issues whatsoever.
But suddenly a few hours later, I couldn’t take off anymore. Sometimes it allows me to throttle up for take off when I start the flight scenario, but just about 8 seconds later it goes back to zero and holding A won’t accelerate anymore. Clicking the physical throttle inside the cockpit and moving it forwards will work as long as I keep pressing, because once I release my finger it’ll go back to zero instantly.
Today I tried it again, and I can take off but as soon as I’m in the air, the plane just goes full left and crashes without responding to any of my inputs. Throttle also goes to 0% or 100% by itself.
Tried setting a deadzone for the analog sticks, but this made them not even being able to act as cursors in the menus.
After a lot of patience I managed to reset the controls to default, but soon the problem returned and the planes were making full turns by themselves or zeroing throttle and some keys stopped responding (like the change camera view one between 3rd and 1st persons).
