While operating Aircraft X; we experienced loss of thrust in the right engine while we were leveling off at 8;000 ft on the ZZZZZ 2 Arrival into ZZZ1. Earlier that morning; when we started the engines in ZZZ. We noticed that the right engine was approaching a hung start; however; it stabilized while it was still within the limitations. The Captain and I confirmed that the engine had stabilized and all engine indications appeared normal. Everything remained normal until our arrival into ZZZ1. The Captain was Pilot Flying; and when he increased thrust to arrest our descent and level off at 8;000 ft; we noticed that the right engine did not respond to the thrust lever. The thrust remained around 30% N1 regardless of the thrust lever position. We then notified ATC and requested radar vectors. Once we were on vectors; we ran the QRH for 'Thrust Lever Inoperative' 1-34. After discussing the situation; we determined that since the thrust was remaining at idle; it was in the interest of reducing complexity and increasing safety to keep the right engine operating at idle. We then ran the 'Single Engine Approach and Landing'  QRH 1-27 and configured accordingly. We continued the approach and landed uneventfully. We advised ATC that we did not need assistance taxiing to the gate. Once we arrived at the gate; we performed the shutdown procedure. When we shut down the right engine; it took multiple attempts to get the thrust lever to shut the engine down. After completing the shutdown checklist; we advised Maintenance of the issue.
First Officer reported unable to control engine with thrust lever; resulting in a precautionary emergency landing with the engine remaining at idle.
