WebThumbnailExtension Web Content consumes all memory

Question

WebThumbnailExtension Web Content consumes all memory

Hello all,

I'm using my M4 Mac Mini for a week right now. Sometimes, I have troubles when I use Safari. It keeps creating WebThumbnailExtension Web Content instances non-stop. Even though I have 1 or 2 tabs open in Safari when I click another website it creates another instance of 1 GB WebThumbnailExtension Web Content and I don't even have any extensions built-in Safari. Although I force quit every instance, Safari re-creates them. After doing this for like 20 minutes, Safari gave up creating them but I don't know why.

Here is the screenshot from Activity Monitor.

I'm using macOS Sequoia 15.1 (24B2083)

I noticed something. When I use Spotlight, it also creates the same instance. Also, this instance's full path is: /System/Library/Frameworks/WebKit.framework/Versions/A/XPCServices/com.apple.WebKit.WebContent.xpc/Contents/MacOS/com.apple.WebKit.WebContent

Have you installed any third party AV-ware or a VPN on the new Mac mini...?

If not, then perhaps something Migrated over from your previous setup...?
