Remote Play (PC to PC) Controllers not working

[MDVL]

I've come across an issue with remote play via PC to PC, where controllers do not work.
-They work while streaming any other game.
-They work while running the game on host PC directly.
-Drivers are up to date on both PCs and controllers.
-I have tried every different config of Steam input options.
-I have tried PS4, PS5, XB1, X/S and Generic.

The controllers all work right up until you hit the main menu. Then the only buttons that function are the Xbox/PS buttons to open other menus.

Keyboard and mouse work once I am there, but there doesn't seem to be a way to get the controller to function.

Has anyone run into this?

I have the same issue and some others on reddit, too. Seems that there is no solution right now. :(

remote play is not working atm - hopefully the devs fix soon. Comment on others with the same problem to bump the topic.

yea same here, the controller implementation is also god awful. i dont know how they botched this compared to the first one which worked fine with PS4 controllers. you cant get ps4 controllers to work wirelessly even with DS4Windows. it all has to be through wired and steam input disabled which is god annoying

Same problem with backbone and steamlink

Same issue here

Edited to add workaround:
Connect local wireless remote to PC and turn on (mine is one with a 2.4 dongle)
Disable steam input under Kingdom Come game properties in controller tab
Make sure to keep the local wireless remote powered on - but no need to use it (very laggy far from PC). However while it stays powered on, the bluetooth controller connected to the Steam Link session works even within KCD2. If the local wifi controller falls asleep, the remote bluetooth controller stops working in game/mid-step. We have to wait for a bug fix, and use this clunky workaround in the meantime
