Do you have the same issue if you follow the OP’s steps to reproduce it?
Yes
Provide extra information to complete the original description of the issue:
Single engine taxi is difficult or impossible in the ATR, which is unfortunate because it is a normal procedure IRL. This is also true of many aircraft in MSFS due to the modelling of wheels/tires. Because wheels are modeled as points of contact with friction determined by the type of contact and not in a more sophisticated way (as actual wheels), differential thrust/braking has an exaggerated effect. Steering the nosewheel also adds drag which exacerbates the effect of reduced thrust from only having one engine running.
