WebThumbnailExtension 100% cpu usage

I'm having a problem with my macbook pro m1 pro, when I turn it on it starts to run slow and when I open the activity monitor I have at least 10 processes called "System/Library/Frameworks/WebKit.framework/Versions/A/XPCServices/com.apple.WebKit.WebContent.xpc/Contents/MacOS/com.apple.WebKit.WebContent" and "WebThumbnailExtension Web Content" I don't know what this is, I can't find a solution.

MacBook Pro 14″, macOS 15.0

This is causing a huge problem for me! My brandnew Maxbook Pro with an Apple M3 Max now just completely blocks for several minutes, several times a day. That is completely unaccaptable. I see about 10-20 of the same processes with this path:


/System/Library/Frameworks/WebKit.framework/Versions/A/XPCServices/com.apple.WebKit.WebContent.xpc/Contents/MacOS/com.apple.WebKit.WebContent


Parent Process: launchd (1)


Apple please fix ASAP! Thanks!
