Video Editor workspace doesn't load

You need to provide details for anyone to help

Exact version of the operating system

Exact Premiere Elements version (any updates applied?)
CPU brand and model and clock speed
Amount of computer memory (RAM)
Video adapter brand and model and driver version and amount of video ram
Number and size and type of hard drives

Do not count on Windows to be fully up to date when it comes to device drivers
Go to the vendor site to be sure you have an updated driver for your graphic adapter
nVidia Driver Downloads https://www.nvidia.com/Download/index.aspx?lang=en-us
-for Premiere Pro (and MAYBE Premiere Elements) use the STUDIO driver, not the GAMING driver
If you have a laptop you MAY also need to check for a laptop specific nVidia driver
AMD/ATI Driver https://www.amd.com/en/support
Intel https://downloadcenter.intel.com/product/211969/Intel-HD-Graphics-Family
There are also intermittent reports that the newest driver is not always the best driver due to driver bugs or compatibility issues, so you MAY need to try an earlier driver version
