Hello Cowgill,
Welcome to Microsoft Community.
CRITICAL_PROCESS_DIED is a common blue screen error message. This indicates that a critical system process died. A critical process is one that forces the system to bug check if it terminates. This can happen when the state of the process is corrupted or otherwise is damaged. When this happens, as these processes are critical to the operation of Windows, a system bug check occurs as the operating system integrity is in question.
I confirm that you have tried many ways to fix this problem, but you still can't log in to the system normally and you have been stuck in the "automatic repair" page. Can you see "Advanced options" at this time? This option include "Reset this computer" and another "Advanced options". "Reset this computer" is a currently available operation, please click and try to reset according to the prompts, please select "save personal files" according to the prompts.
Resetting the system is also a regular fix, and usually when the reset is successful, the problem can be resolved. However, if you find that the problem occurs again and again after you have logged in to the system, or if the reset fails, I recommend you find another device to create a USB installation media, and then use the installation media to reinstall the Windows 10 system.
- Prepare a flash driver with at least 8GB (Pay attention to backup data, because creating a boot disk will erase all data of the flash driver). Then operate it on another Windows computer.
- Visit Download Windows 10 (microsoft.com) **** and click "Download Now" under the "Create Windows 10 installation media" to download MCT (Media Creation Tool)
- Run the MCT, select "Create installation media (USB flash drive, DVD or ISO file) for another PC”, and then choose Language, Version, Architecture (if you are not sure about these, choose "Use the recommended options for this PC"), then select "USB flash drive" in the "Select Media to Use" interface, then make a USB installation media.
- Then boot from the USB installation media, and follow the prompts to reinstall the system.
If anything is unclear, please do not hesitate to let me know.
