For no good reason, one of my engines throttle stop working!

These are one of the times this has happened to me. in calibration, everything seems to be alright!!

I was flying on a Singapore Airlines B777-200 going from Jakarta to Changi. For most of the flight, I was on autopilot. When I took off, I used manual controls and my throttle worked fine. When I tuned to the runway's ILS frequency, I turned off autothrottle. I put the throttles down using the joystick, bu only engine #1's throttle went down!! The other engine's throttle didn't respond!! I had one throttle on max, and one on full!! I was caught totally off guard and entered a spin and crashed. This has happened to me quite a few times and can be very frustrating during landing. Even with the keyboard, both throttles don't work, only one does. I have to manually drag the throttle from the instrument panel which can be frustrating. I am using a Microsoft Sidewinder Joystick. Any help would be nice,
thanks

No matter what joy stick i use, sidewinder 3d pro, logitech extreme 3d pro, saitak you name it.
but, it only happens when i restsart and i hafta fire the motors ta get em goin cuzz the auto wont flip the fire button when its supposed to 😕

If its anything like fs 2004, its because you are
bumping what i think is the E key, which selects engine 1.

Let me fire up fs and check

Yeah if its the same in FSX as in FS2004, under the control assignments under engine controls the E key does engine select.

I always used to bump it, and it selects only engine 1 for the throttle control, best bet is to re-assign it.

are you saying reassign control + E for the auto start?
(i have a habit of hitting the "A" key when i try to engage the autopilots "Z" key)
(and i did reassign my spoiler key to /) i forget why but it must have been for a similar reason 😂
but, is there someway to reset that without having to restart the flight?(the throttle troubles)

I couldnt find a way to fix it in flight apart from changing the E key. The way engine select worked was you would press E, then press a number 1-4 on which engine you wanted to select from your throttle. Not sure how to reselect them all.
