Premiere pro encoding does not work..

Hi could someone help me with this issue I have.. I have been using this app for the past 6 months on my laptop and it has worked perfectly fine... no issues but now it won't finish encoding as it is stuck at 0%

Laptop spec:

Dell inspiron 14 5410 2 in 1

8GB ram (upgrading to 16 in 1 month)

512GB Nvme 3.0 SSD (40% full)

Intel Iris Graphics (2GB)

Nvidia Mx350 secondary graphics (1GB or 2 GB)

Intel I5 11th Gen 10k smthn..

Windows 11 64 bit

I normally render My videos by exporting on premiere pro or sending it to media encoder.. it used to work fine but not neither one of them export properly .. I use Mercury playback engine hardware accelerated (CUDA) but now that option is missing so I use (OpenCL) then it stopped working? Usually I render the vid on H.264 on medium or high bitrate at 60fps and 48Hz audio stereo channel. 

Please do help me ASAP since I am a yotube content creator and really need this to be fixed 🙏 😢
