Cant access steam client since 2 days

[drtydz]

So i just reinstalled windows and cant seem to get steam running.

Im always getting the fatal error message "Could not load module 'bin/Filesystem_stdio.dll'

I reinstalled windows 10 like 3 times now and always get this error message.

If I start the client it wants tp update, then the update fails and Im getting this error message.

Sometimes it even says "failed to load steamui.dll.

Copy the error message "Could not load module 'bin/Filesystem_stdio.dll'" and paste into google.
The first item shown should answer your question. (reinstall steam)

in case your google isn't finding it:

I already did google the issue but nothing of the mentioned fixes worked for me

Use steam flush command google it.

Add steam.exe to exception rules. In programfiles x86 Steam

I'm having the same issue after installing Steam on a new computer and none of the above fixes have solved it. I have fully reinstalled Steam multiple times, making sure that all traces of it are gone from the machine each time. I've tried SFC/DISM, all of it.

I get "Could not load module 'bin/Filesystem_stdio.dll' when starting Steam.

Sometimes if I restart it enough times it'll open but all the screens will be black.

I think they broke something with the client update from december 16th.

Wow, unfortunate that this is happening, but I'm glad I'm not the only one experiencing this! I just made a Reddit thread with more detail, but I've also been having this happen the past few days: https://redd.it/rmlr05

Steam was fine for years with my RX 580. Got a 3060 yesterday and reinstalled Windows, and have been having all sorts of issues with Steam, including all 3 issues listed in this thread (steamui.dll and FileSystem_stdio.dll errors, and black Library/web views). I just assumed NVIDIA was to blame in some way since that's the only major thing I've changed.

I am having the same problem. The 12/16 update wouldn't install, it kept reverting. Got tired of having to wait the extra couple mins each time I launched steam so did the "delete everything except steam.exe and steamapps". Got the "Could not load module 'bin/Filesystem_stdio.dll' error when starting Steam. Retried deleting everything 3-4 more times, sometimes also deleting everything in AppData/Local/Steam folder. After 5th (or so) attempt I got to the login screen, but now Steam content window in app is blank (menus at top are there + footer is there) and app is unresponsive. Will continue trying different things

[natethelen]

One thing I did differently the last time was to make sure and empty recycle bin. Maybe some file was still somehow referenced

[natethelen]

Tried: moving steamapps outside the Steam folder, deleting EVERYTHING, re-downloading steam installer, uncheck "run steam" after install, move steamapps back in, launch steam, got the "Could not load module 'bin/Filesystem_stdio.dll'.

This time I just kept launching steam.exe and each time it would do something different, downloading different updates. Eventually got back to login screen, but still have blank content window and unresponsive app.

Last thing to try is to completely uninstall Steam, including all steamapps, and starting fresh. Sucks to have to redownload everything but out of ideas

[natethelen]

Did that, same problem. Did another complete uninstall, restarted computer, that worked. Possible (likely) that if I had restarted at some point in the many other attempts I would have been successful. I hope this helps someone someday :)

1. Try to disable ur firewall and antivirus, then try to launch steam and see if the problem is solved.
2. if "1" doesn't work then u better try to reinstall steam as it could be the fastest solution
Hope that helps.

I think I found what causes this. If your ssd is formatted with a sector size of 4kB it is causing this issue. I replaced my corsair mp600 , that was formatted with 4kB, with a samsung 980 pro that only supports 512B format size.

Now everything works normally again

I can personally test this within 2 hours with a Hynix P31; I know I went out of my way to get my NVMe SSD in native 4K sector size but can easily switch it back to 512e mode.

At the very least, I've tried Windows 11 Dev, Release, 10 LTSC 2021, 10 21H2, and 10 LTSC 2019. Steam has consistently failed to work on every OS except LTSC 2019 (1809), so I'm thinking if that sector size toggle doesn't work, another solution is to go back to 10 1809.

If the sector size is the problem, then this is likely to have started within the last month or two with a Windows update in both 10 and 11, or only affects certain hardware combinations.
