Same issue others are experiencing @Rattgtg - I was trying to do things using shortcuts - thinking that the player data available in the .ark file was enough to identify things. Turns out some players in the .ark file have weird NetId that then causes ASV to crash attempting to find that matching .arkprofile file.
I'm in the middle of re-writing it to work similar to how the old version worked, reading data from .arkprofiles first, then the .ark file.
Hopefully have you an update out this evening but busy playing atm.
