I used my world seed to regenerate the world fresh and plugged in the coordinates and the place it points me to errors out every time. 

It opens other chunks just fine. This is in a freshly generated world with a monument in the same spot so i know the seed is correct. This new world has also failed to generate the Monuments.dat file within the data directory. Not sure if that is related or not.

I have never navigated 'region' files. I don't know how to do this. Have a good link that explains this process?

I could really use some help here. I had drained out an ocean monument while on 1.15 and then built a guardian farm in it on snapshot 20w21a and my momument no longer spawns guardians. Structure blocks aren't big enough and i have had no luck getting NBTexplorer to even run without crashing.
