Unexpected file format """""""

Hi, im experiencing the unexpected file format on may skp file and skb file, can you help me fix it?

Your profile makes me suspect that you are using a cracked version of SketchUp. “Free plan 2021” does not exist.
Your file opens, slowly, in the latest version of SketchUp 2023 without problems. You have managed to stuff a small house design with a ridiculous amount of entourage stuff, amounting to about 10 million edges and faces.

Upgrade to the latest sketchup version and it will open, you have a lot to purge and optimize, the models you downloaded are overkill.

can anyone help me to fix my unexpected file format
