Rendering Crashes - Can't Stop, Won't Stop (Dn + Sg)

Hey Adobe-fam,

I've had projects piled up that depended on the success of Dimension's renderings, that now I am over a month behind on work. After months of having issues with Dimension not finishing a render past 50%, I decided to try out Stager. Tried it, it worked for a render or two. Now, it's back to what dimension's problem was:

After the rendering reaches 50% it goes to :01, 0% and stops. Computer CPU fan turns off, etc. Application still responds to button clicks and restarting the renders, but NEVER completes. 

Equipment Specs;

AMD Ryzen 7 3700X 8-Core Processor 4.05 GHz

NVIDIA GeForce RTX 2060 SUPER

16.0 GB Ram

64-bit operating system, x64-based processor

I need to explain the failures and extra cost now to management, so I will need a solution from your team or a full refund. This is not tested well enough to charge $50-75 more per month and should be considered for further beta testing until it is able to produce consistent results.
