Steam won't launch

[CapMazz]

I've done all the stuff they said on youtube yet didn't solve anything, I format the PC and it start normally at first after I restarted the PC to finish the setup It didn't launch at all

It's to do with the client switching to 64bit.
Lost of people are having similar issues.
Message Steam on X to help push visibility for the dev team I guess.

Edit - Also are you on win 10 or win 11 ?

Curious - Do you have a XBOX or similar controller plugged in?

Yeah there is a controller plugged in

Try unplugging the controller. Start steam, then plug it in. See if this works. I have read this method works with others.

i had this issue and disconecting the controller worked, but the controller isnt recognized anymore by steam for some reason, it works fine outside of steam

I’m having the same issue. I updated the client on Windows 11 this anfte and now it will not run. I’ve reinstalled Steam atleast six times and nothing. It shows up as a background process but nothing more.

Steam won’t run if my gamepad is plugged in. 8bitdo. If I unplug my gamepad… Steam will boot. But it won’t recognize UI input in the Steam client from gamepad. But then if I actually boot into a game, the game will recognize gamepad just fine.

The new client is a hotmess when it comes to gamepad support. Was working just fine prior to the recent update.

Most likely the transition from 32 bit to 64 bit support broke the controllers as it was the same update. Contact the developers of the controller and email them explaining about this update. They may have to make a new firmware update to fix this issue on their end. I highly doubt steam will fix everyone's controllers, so it is best to work with the developers of the specific controller your having issues with and explain the situation to them.

I doesn't appear to be an issue with the drivers / firmware / controllers themselves. As many people have confirmed now that their xinput devices still work fine with games and other apps. The theory (as of right now) on reddit is that it's either a problem with the hardware handshake when on 64bit client - or some issue with big picture crashing things while a controller is connected.

I think it has something to do with the 64 bit architect client too.

Although i have found big picture can be weird too, but im leaning towards the 64 bit architect change messed it up, like the handshake like others think.

Oh yes, definitely - the switch to the 64bit client is undoubtedly the cause of the incompatibility.

Yes, i suggested this in other posts too, about the change to 64 bit architect has caused it. Hopefully steam will fix the issue in the next patch. I am unsure if they will or not, but i guess if enough people complain about it, like the posts earlier this year someone made about the steam overlay crashing people's games did, from tea garden did, they may fix it.

Yeah I really hope they push out an update revision, like they did with the last two client updates in Oct & Nov. I just hope they classify it as a category 1 bug, and not a lower category bug, because it has a workaround. Cat 1 bugs usually always make it into update revisions days later - where as lower Cat bugs are often deferred for weeks, if not months sometimes :(

You can keep an eye on the below beta update thread in order to know when new fix's are on the way to the stable branch (main public client branch).
