Symptoms

Game gets stuck and controller reconnection causes it to wake up. Can't play campaign, only menu working.

Reproduction

Well, I've bought this game because former Strike Vector isn't working, besides being old. Strike Vector EX isn't working too. The game launches but gets stuck after the two initial banners in a spinning wheel screen. Controller reconnection causes the game to wake up and report controller disconnection, it works to past this. The game menu and settings setup works fine, but once entering the campaign it gets stuck again, controller reconnection works to bring a menu to exit to main menu, but the game campaign simply refuses to start.

From log it looks like the game hangs when failing to play media files, the two times it gets stuck, one on launch and another on campaign start, seems due to that:

Oh, why haven't I searched this GitHub repo for Strike Vector related issues for so long... (Didn't expect anyone to submit it, honestly.)

We have known for long time that the game is mostly working, and the intro video can be bypassed (add ?nologos to the launch options).

Unfortunately, the campaign is still unavailable because of unplayable videos, only multiplayer is available.

I wonder if the meta-issue #1464 is relevant. I think it should be, considering #327 and #1571 are there (other UE4 games). The proton log attached to the issue seems to have mf.dll and mfplat.dll mentioned.

@KillyMXI thanks for pointing #1464 out, surely it's the same problem.
