Noticed the same error, friends list seems to work correctly tho. Tried deleting all the other files too such as cache/themes/plugins. The issue persisted.

Steam has recently changed something in the beta channel that breaks the Millennium UI. switch back to Steam stable in the time being. Steam -> Steam Settings -> Interface -> Beta Participation

[hai-kacper]

Thanks, I've gone ahead and done that for the time being.

You can also run steam -clearbeta in a terminal to revert to stable, if you are unable to access the steam settings ui

Use this:
Win+R steam://open/bigpicture

You can also run steam -clearbeta in a terminal to revert to stable, if you are unable to access the steam settings ui

"steam:// -clearbeta" from the Run window did it for me

Fixed in 2.29.3

Fixed in 2.29.3

Now extensions in Extendium seem to not work or not have access to pages. Is this an Extendium issue?

[shdwmtr]

No, we missed a discrepancy when releasing 2.29.3. I'm releasing a new version as we speak
