Hello
If the model you created in other view can be viewed in perspective view
Then you can click on the "+" in the upper left corner of the viewport ? In the Viewport Settings pop-up, switch to the Background panel and choose to use a custom interface gradient color
If you can't view the model in perspective in other views, it may be a problem with the graphics driver or the software's display driver
Try updating the graphics driver to the latest version, then go to the Customize - Preferences - Viewports section and click on "+" in the upper-left corner of the viewport. -Preferences- Viewports, change the display driver mode (I'm using the software's recommended Nitrous mode)
