Media Encioer on macbook pro took more than 40 hours and seems stuck

Hello,

I'm trying to render an after edffects project on my macbook pro 

MacBook Pro (16-inch, 2019)

2.3 GHz 8-Core Intel Core i9

16 GB 2667 MHz DDR4

AMD Radeon Pro 5500M 4 GB

Intel UHD Graphics 630 1536 MB

Using Media Encoder 22.0 build 107

I enabled hardware acceleration (metal) (I don't see opencl as an option)

I enabled parallel encoding 

i left only 3GB for OS (out of the 16GB RAM)

For some reason the media encoder seems stuck - it takes CPU but the time to completion is just getting longer and longer 

I'm using a 3D template from Invento Elemnts 

This is beyond annoying since I can not meet my deadlines this way.

Thanks,
