Same here since Friday CET (11.07.2025).
Yesterday everything worked fine. Didn't change anything (system, network, etc..).
Have this Issue even on steam deck - infinite loading of user data.
Tried many things (Restart, Reinstall, System rebuild) and nothing helps at all for me.
My wife's account works fine on all devices where my account doesn't work at all.
Never had such an issue in my history of steam account (15 years).
No idea what steam did it - but they broke something badly and it seems for many users.

It seems this problem is not related to PC environment. I tried to test login to 3 PCs. But same problem was happened.

ask steam support for a account refresh, they refreshed my account and i can login again without problem

Having the same issues here and tried all the fixes with mix results. I am betting everyone having this issue has older accounts. Can everyone confirm how old their accounts are? I think the one in question for me is between 10-15 years old.

My account is about 15 years old.

Try the above.

- In Steam folder: Move "userdata" and "config" folder to the desktop temporarily. Then in task manager close any instances of Steam that might be running. Try relaunching Steam again. Re-Login and see if that works.


- Second option could be removing everything apart from "Steam.exe" and "Steamapps folder". Once you do that just run steam.exe - It will reinstall steam, and you won't loose the games.

LOL! Watch, it's all the OG gamers that this is affecting.

1984

1988, if they dont fix it soon I might call on them for elderly abuse.

Same issue here
I made new account and it worked.
I think steam server or user data server problem

See, they probably have updated their back end. Some major changes to codebase I assume. Legacy players are affected.

They might be getting aware of it just now due to community backslash. Give it few hours. I guess it will be fixed in a day or two. I'm an API dev for different game and I've seen some of similar issues in the past.

i am still stuck on the loading user data page. nothing i’ve done has helped. i sent in a helpdesk and haven’t heard anything back

It worked, so I wonder if it would work for you as well.
-no-browser should disable the store, community and other things that require the browser, so it's not a permanent solution, I fear.
It didn't disable them for me so I actually have no idea what it's supposed to do, but I also know disabling the browser sandboxing is a security risk.

Hey, I didn't thought about this. After removing the arguments it booted as usual.

I guess this will be temporary fix if this ever happens again.

Thank you friend.

Can you walk me through how to do this on my computer?

Right-click the Steam shortcut on your desktop and select Properties.
In the window that opens, look for the Target field (usually the third box).

At the very end of the existing text/location in that field, add a space and paste the following:

-no-browser +open steam://open/friends

Click Apply, then OK.
Make sure your steam is already closed. Try to run through that shortcut.

This will force Steam to open directly into your friends list and avoid the broken browser view that's been stuck on loading.

Let me know if it works!

I'm glad to hear it worked for you as well!

Steam support told me to switch to the beta by adding it as an argument to my shortcut but it's working fine for me now so I think I'll just wait and see if it stops working again.

I highly recommend anyone having this problem adding the arguments, launching Steam, closing it and removing them to see if it keeps working when you launch it again.
