NUC crashing frequently, showing PXE-E61 and PXE-M0F error messages

[Lorin]

My Intel NUC boots up fine, so my problem is different from the ones posted in 2016. But the error messages I get are the same: 

• PXE-E61: Media Test Failure, check cable
• PXE-M0F: Exiting Intel Boot Agent.

The difference is that I don't get these error messages during boot up. Instead, my Intel NUC (running Windows 10) crashes, then shows the above error messages. However it also adds this message:

• Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key.

What should I do to stop the Intel NUC from crashing? When it does crash and shows the above messages, what should I do? So far I have solved this by doing a hard shutdown, then pressing the power button to boot up the computer. At first it was crashing once a week, then nearly once a day, and now it's crashing once or even twice a day. The problem began about 3 weeks ago.

Thanks!

On the back of the NUC I see the following:

Product code: BOXNUC7i5BNH

Installed RAM: 8.00 GB (7.89 GB usable)
Product ID: 00326-10000-00000-AA353

Installed on 3/18/2021

I looked up CRITICAL PROCESS DIED on Microsoft's support site and it said I might have downloaded a new program that's making the computer crash. I don't think I have downloaded any new programs since I installed Windows 10 when I got the computer 3 years ago. 

I get a blue screen I get when the computer first crashes. It says "Your device ran into a problem and needs to restart. We're just collecting some error info, and then we'll restart for you. For more information about this issue and possible fixes, visit https://www.windows.com/stopcode".  If you call a support person, give them this info: Stop code: CRITICAL PROCESS DIED."  

Thanks for your help!

Here are screenshots showing the initial "bluescreen" and then the screen that eventually follows the bluescreen.
