I've finished what seems to be a complete port of the IPHLPAPI.dll BLT hook to the VR Beta. It's also compatible with the standard version, so you don't' need to swap around when switching between the VR Beta and the flat version.

Install the 'mods' folder from the normal version of BLT - that part doesn't change. Then download the hook (IPHLPAPI.dll) from below and put that into your PAYDAY 2 folder, instead of the one that came with BLT.

BLT will nag you to update - do not do so. That will revert you back to the standard version of BLT, and you'll have to download and overwrite the DLL again.

While I made it work with the VR Beta, that was a thousandth of the work it took the BLT team.

1) Make sure you have the latest version of the hook DLL
2) Remove all mods other than the VR Improvements mod (if this fixes it, put them back one at a time until you find which one is causing crashes)
3) Remove your mod_overrides. If this fixes it, do the same as above putting the mods back one at a time to find the culprit.
