This recently started happening, and every time it crashes I get this error. I tried running diagnostics but I get another error saying, "Cannot Load EFI/Drivers/TestSupport.efi"

I have a MacBook Pro (Retina, 15-inch, Early 2013)

macOS Catalina 10.15.7

2.4 Ghz Quad-Core Intel Core i7

16GB RAM

Intel HD Graphics 4000 1536 MB

Anybody have any ideas? Thank You.

The Kernel Panic is referencing a GPU issue which 15" models are notorious for plus the 2013 model even had a free repair program at one time (now expired). You can try to force the latpop to use the Intel GPU instead by using gfxCardStatus app (you may need to install it while booted into Safe Mode):

If you cannot boot the Mac normally or into Safe Mode, then you can use the instructions in this article to force the laptop to use the Intel GPU:
