[2020] Game freezes. Can anyone help? GMs don't know what's wrong - really need help QQ

I will make a guess - there is a drive error (SSD or HD - doesn't matter) when loading those assets which eventually recovers (which is why it happens in the same place every time). If you're comfortable with moving stuff around on your computer, you can make a copy of the .dat file (Gw2.dat which will make GW2 - Copy.dat). Then delete the original .dat and rename the copy back to Gw2.dat. Of course, for this to work, you need an extra 50 gigabytes of free space to make the copy.
