To ensure games run well on Linux either via Native Linux builds or Windows games with Proton, part of the magic is in the Steam Linux Runtime. A new version of it, the Steam Linux Runtime 4.0 was recently put up with some pretty big changes.

What's the point of it? It ensures Steam and games run through Steam on Linux work properly across all the many different Linux distributions. Another secret Valve sauce for Linux. Well, not secret at all but you get my meaning I'm sure.

I think it might have been a denial of service type thing as explained in other replies. I didn't reboot or anything and it just worked fine now. All good. 👍 Thanks for all the help though.

Almost every reply is also explaining what the runtime is. 😆 I know what it's for, guys, thanks! ❤️🙏👍

Glad you got it fixed. 🙂

I boosted it up a bit for other people who come along w/ a similar concern. You seemed mistaken at first until a few threads deep, so there's likely someone else who is just as, if not more, confused.
