Panic Report Help on mid 2010 pro

Pretty much mentions the GPU in the first lines with references to Nvidia further down.

Try starting up in Safe Mode,

This will run disk repairs and clear caches, it takes a long time

to start up in Safe Mode so be patient.

Restart normally.

Then try this, Reset NVRAM or PRAM on your Mac – Apple Support

Click on the top left of your screen select About this Mac and take

a note of the graphics card details, go to the Nvidia website and see if there are

any drivers available for the OS and mac you are running, install if any

see if it makes a difference.

You could try reinstalling High Sierra again, you do not need to erase your mac first just install it over what you have.

Get the High Sierra installer here,

Open Safari and click on this link,

How to get old versions of macOS – Apple Support

Go to Download OS and click on macOS High Sierra

this will redirect you to the App Store High Sierra page it should say Get or Download.

Back your mac up before you reinstall the OS.

If these don't work and you do not get any further forward with anything I have mentioned

or any other contributions from other it may be time for a new mac as the graphics cards in MBPs

cannot be replaced.

I suspect a failed GPU. You Mac is the right generation to suffer failing discrete GPU.

Try gSwitch and force the use of the intel integrated graphics

The other VERY remote possibility is that you seem to have 3rd party RAM

Corsair Mac Memory — 8GB Dual Channel DDR3 SODIMM Memory

Sometimes failing RAM can cause issues, But it is much more common for your panic to be related to a failing GPU, so I would go with gSwitch and disable the discrete GPU.
