Error 301 / 302

[Juice Box]

I use a Vive, and everything's been working fine until I tried to launch SteamVR last night.
It opens black at first, then shows the usual tab with no devices connected and the debug open, and the message "SteamVR Fail A key component of SteamVR isn't working properly."

I've tried everything from total re-installs of Steam SteamVR and Viveport, running as admin, deleting files, cmd system scans, full restarts, starting with everything unplugged, everything suggested either in the support or online.

The best I can tell is that vrserver.exe fails to run, and attempting to run it does nothing so SteamVR is just starting and all of it's faculties close out or fail to run.

Here's the vrserver.txt Logs

Update, I've just done a full wipe and reinstall of Steam, SteamVR and Vive.
Started up SteamVR to the same error but hit the button to reset the headset, and it opened normally and told me to connect my headset. When I cycled power to my Vive Box it crashed immediately.

Update, uninstalled and reinstalled Nvidia, no changes

There's a couple things here under 301 you didn't mention
SteamVR support wizard https://help.steampowered.com/en/wizard/HelpWithGame/?appid=250820


And there's these prior fixes for 301 in the forums:
1) Fix SteamVR install path ( https://help.steampowered.com/en/wizard/HelpWithGameIssue/?appid=250820&issueid=374&nodeid=40&return_nodeid=71 ) or reinstall steam ( https://steamcommunity.com/app/250820/discussions/0/3825286048534020436/?tscn=1680835690 ), or update quest drivers and reintall steamvr ( https://steamcommunity.com/app/250820/discussions/2/7260435610014887632/?tscn=1708472728 ), wipe and reinstall steamvr ( https://steamcommunity.com/app/250820/discussions/0/6629936675071577513/?tscn=1713158309 )
2) change 4k monitor to 1080p ( https://www.reddit.com/r/Vive/comments/4iodmz/my_error_301_fix/ ) (last post)
3) launch games through the meta quest app ( https://steamcommunity.com/app/250820/discussions/0/4299320559086483870/?tscn=1709990941 )
4) update GPU driver ( https://steamcommunity.com/app/250820/discussions/0/4299320559086483870/?tscn=1710047300 )
5) Repair oculus installation ( next post in above link )
6) Update Quest Headset ( next post in above link )

Did all of 1, I don't have 4k monitors, I don't have meta quest, GPU is updated, I don't have Oculus or Quest.

Also like I stated I've done everything in the official Support section already.
Also tried disabling integrated Graphics, reinstalled C++ redists both 64 and 86
