Steam took over my computer and thinks it's a Steam Deck after update?

[GR G-Boobie]

Hi folks. I'm running a Win 11 PC with 13th gen I7 intel CPU, 64 gigs of RAM, Nvidia 4070 RTX, and two 2 gig NVe SSDs. Rig is a month old. Clean windows install, built myself. Steam has been fine up until an hour ago, when it updated and launched in big picture mode.

Not only was it in BPM, but when I moused to settings to exit BPM, it would randomly detect inputs and bring up other side menus. After exiting BPM, I minimized Steam. It would then randomly un-minimize and change the focus to itself, along with getting the same random inputs.

Restarting Steam did not help. Restarting Windows did not help. I ended up deleting Steam (and 2 gigs of game files) and reinstalled it. When it went to reinstall, it tried reinstalling in BPM with Playstation inputs (no PS controller is on, so this is double weird). I couldn't even sign in because of phantom inputs constantly pulling me away from the QR sign in screen.

Steam is currently exited and the PC is running fine. I'm typing this on my gaming laptop, which is also running fine. This is driving me crazy: I cannot stress enough that Steam was working absolutely fine on the PC last night with no hiccups, and is still working on my laptop with no issues. The PC was $2500 and a labor of love and I'd like to understand what the hell is going on so I can get back to using it for it's intended purpose.

Any ideas?

Thanks in advance.

Doing a complete reinstall of Win 11, hopefully that resolves it, though I’m salty as hell about having to redownload eveything.

The symptoms sound exactly like what would happen if you were using a controller/keyboard mapper or Xinput emulator tool that was misbehaving in some way, but being a month old I'm sure you'd remember if you did any strange controller-related stuff?

Open Steam's settings and go to Controller.

If you don't have a controller connected, it should say there are no controllers.

If it DOES show a controller connected, the issue is likely what I already described and at some point you've installed something like joy2key, joymapper, x360ce, ds4windows etc. which is causing their virtual controller to show as connected.

Interesting. I did plug in two arcade sticks, one is an older custom stick with a PS360+ custom board (the other is a VictrixPro PS5 official release). For controller I have an Xbox Elite v2 using the official app and drivers. I didn't install anything specific to 3rd party controllers, but maybe when I plugged in the arcade stick it got weird?

Appreciate the input, when I get everything reinstalled and if I'm still seeing the issue, I'll come back and confirmed.

OK, windows reinstalled fresh, Steam re-downloaded, everything is copaceptic. I'm going to plug in the sticks again and see if I can duplicate the issue

[GR G-Boobie]

OK, the old stick is the problem. It's wild: whatever driver Windows uses when I plug it in gets stuck and creates the problem. Solved, thanks folks.

I'm also having this problem, but steam deck won't even recognize there's an internet connection so I can't go into steam's settings

Do you have Family share in top of this, we are not support here, but it look like that from other post with semisame issue with FS, and we have to best guess here.

Other FS issue is you have issue with it then you do, and could make alot of sense why things not working, as i said pure gussing, with no clue what you have and do.

if not then you have other connection issue in own steam server though your ISP, because you just got out of steam autumn sale even that make sense within next 2 days most DL traffic return to normal.

Just to make sure we had the same issue: Steam thinks your PC is a Stem Deck? My resolution was an old driver for an old custom arcade stick. I had to entirely wipe my PC and redownload everything. But before you do that, unplug and uninstall any controller and driver for controllers then restart the PC and see if that works.
