Package error blocking Muse Hub installaton

When I try to install Muse Hub, I first got the same "unable to install Windows App SDK" error. I went to download the app SDK runtime manually from Microsoft's official page, and not I'm getting:

"Muse Hub Install Failed"
"Unable to install Muse Hub, please try again. Check the logs
for more information.

Deployment Add operation with target volume C: on Package Muse.MuseHub_1.0.0.624_x64__rb9pth70m6nz6 from:
(MSIX_MUSEHUB.MSIX) failed with error 0x80073D19. See
HTTP://go.microsoft.com/fwlink/?LinkId=235160 for help
diagnosing app deployment issues."

Scanning the link, it seems to refer to ERROR_DEPLOYMENT_BLOCKED_BY_USER_LOG_OFF, but I have not logged off at all during installation. I am on Windows 11. I don't see this as an admin issue as the install does ask for elevation immediately. What's wrong here, and how do I fix it?
