There are some cases where QIDI Studio does not load correctly on Windows. This issue is caused by Windows Media Player feature not being enabled, and it's mostly present for Windows N versions.
Open up the Windows Media Player support page
To enable Windows Media Player in WIndows, select the Start button, then select Settings > Apps > Apps & features > Manage optional features > Add a feature > Windows Media Player, and select Install.
You can refer to the specific content at this link: Get Windows Media Player
After the installation process is complete, reboot your machine, and QIDI Studio should load correctly.
