There is no on board GPU, just and Nvidea Quadro. It is strange that everything works normally until I close and reopen the file. Not having this issue in 2022 only when I switched over to 2023.

I am on 2023 update 3, my toolpaths are all working correctly and I can post the NC. If I close the file and open it back up the toolpaths do not show on screen and will not let me regenerate. I can go into the parameters for each tool path and everything looks good but cannot backplot or post anything.
