There are some cases where Bambu Lab 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.
Here's how to solve this problem.
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 also click on the Enable Windows Media Player on that page, which will open the following screen. Click on Add a feature
In the next window, look for media that will show the Windows Media Player feature. Select it, click install, and wait for it to be enabled.
After the installation process is complete, reboot your machine, and Bambu Studio should load correctly.
