Laptop script error?

Maybe some of you know the game "Star Stable Online". I wanted to play it again today, but when I open this app on my laptop I get a message titled "Script Error". In addition, then open any Internet sites on Microsoft Edge and so on. This morning it was still and not anymore. NEED URGENT Help, Thank you!

Have you changed or downloaded anything? This does not happen for no reason.

No, that's the funny thing. It was yesterday afternoon, not yesterday evening. It was not this morning and not tonight.

Are you the only user of the computer?

Yes

Already checked for errors or running with the administrator?

Yes, I've already done a lot of virus updates, etc
