Switch property 'checked' does not exist on type 'IntrinsicAttributes & SwitchProps'.

[Rijndael1998]

Steps to reproduce

Tested on v6.1.4 after doing a large upgrade from v5.

<Switch checked={true} />

^ this gives a squiggly type error.

Check it out on your own StackBlitz link. Use the "controlled" switch example.

Alert is having similar typing issues:

[Rijndael1998]

Tested with v6.1.5 and it still seems to be an issue. For clarity I'm referring to both the switch component and the alert component.

Same error here, using the @mui/material/Radio component, using 5.15.19
Looks like this bug has been around for a while

I think this is a problem only in StackBlitz because it works for me locally.
