I don’t know what a .webp file is but I don’t like it. They’re like a filthy prank version of the image/gif you’re looking for. They make you jump through all these hoops to find the original versions of the files that you can actually do anything with.
Edit: honestly I assumed it had something to do with Google protecting themselves from image piracy shit
.webp was developed Google so of course Microsoft hates it and tried to hinder it’s adoption.
I can recommend qimgv for an image viewer.
They also don’t, by default, support HEVC and charge you to open them now… it used to be a free app on the Microsoft store.

That’s not on Microsoft. HEVC is not royalty free standard, so Microsoft had no chocie.
