Crash to desktop when joining co-op (GenerationZero_F has stopped working)

Platform: PC Windows 10

Description:

Since earlier this week my roommate crashes to desktop when joining my coop game.

We’ve tried various permutations of joining: from desktop, from main menu, from a running game; from my desktop, from GeForce Now…

All result in a hard crash to desktop with the GenerationZero_F.exe message

We’re both newly installed, unmodded clients, joining a private game.

Gigabit cable connection, both clients on the same network using ethernet.

We’ve both ‘verified files’, and re-installed completely.
Graphics drivers up-to-date.

Just tried again tonight with the same result. It was fine for 12 hours of gameplay last week, but we haven’t connected successfully this week at all.

Steps To Reproduce:

Accept the invite for an already running game.

Any attempt to join the game I host results in the same crash. (all invite methods)

Specifications:
Intel i5, 32 gig ram, gtx 1080

I chimed in on another thread earlier in the week about the identical problem, but perhaps this will get more eyes.

thanks in advance for any suggestions.
