Guess you can't help when you know it's an issue with your program, not my PC.
I found 2 work arounds: Cut the project into 15 minute pieces and render it in chunks, then stitch it together and render it as a whole afterwards, or, the faster method; Use Filmora or some other more reliable video editing software.
I've had issues with Adobe products in the past, but this really takes the cake. Your products are getting worse and worse with each update. Are you trying to fix something that's not broken and making a mess or something? Cause this is hilariously bad.
I will not be repurchasing any subsciptions from Adobe what-so-ever once my subscription ends. I would prefer to invest my money into better, more reliable products.
