Steam not open after latest update

Hey all,

a few minutes ago I updated my steam (size of nearly 500MB) and after that, I got the “steamwebhelper, a ciritical Steam component, is not working.” error. Every provided fix like restart steam, restart steamwebhelper or start steam without GPU accelaration did not help.
The solutions to the problem I found are only windows-specific ones.

Does anyone of you also have encountered the error and know how to fix it?

maybe from this

So far. It appears to still run just fine for me.
