SketchUp itself is functioning well. but when opening Extension Manager, it gives me blank window. Only extension manager window doesn’t work. ![Screenshot (113)](https://global.discourse-cdn.com/sketchup/original/3X/d/3/d373de3ad5545b7527b122f72f5f2325009c9266.png) ---

Try repairing the SketchUp installation. Quit SketchUp, find the installer in your Downloads folder (or download it fresh from here: [Download All | SketchUp](https://www.sketchup.com/download/all)), right click on it and choose Run as administrator. Then when the option is presented, select Repair. ---

Try clearing the Webcache folder in %AppData%/SketchUp/SketchUp 2O21/SketchUp It is a hidden folder. ---

If you are able to open the extension warehouse, you can install a plugin using an eneroth extension that allows you to do it just by dragging and dropping from the desktop or the folder where the file is kept to the sketchup window, I don’t remember the name of the extension right now. ---

The same thing happened to me, and what was happening is that I was working with a second screen on HDMI, but it was off. LOL ---

> [@migue0livares](#): > > The same thing happened to me What version of SketchUp was this in? Your profile says you’re using “Free Plan” of SketchUp 2022. There is no such thing unless you’re using a cracked version. ---
