Close Sketchup. Go to user/AppData/Local/SketchUp/SketchUp 2025/SketchUp and open PrivatePreferences.json. Look for "ThreeDTextDlg". What are the "x" and "y" values? Edit those to move the dialog onto the correct screen. This is what it looks like on my computer.

And here's the dialog relative to the top left corner.

Note that the user/AppData folder is normally hidden so you'll need to make hidden folders visible in File Explorer.
Did you install SketchUp 2025 correctly? That requires right clicking on the downloaded installer and selecting Run as administrator. If you didn't do that it's possible that Windows is preventing SketchUp from making suitable updates to PrivatePreferences.json. To ensure SketchUp is installed correctly, close SketchUp, find the installer in your Downloads folder, right click on it, choose Run as administrator, and when prompted, click Repair. No matter what, it won't hurt to do it.
