Moving this to the Omniverse Nucleus category with Nucleus experts.

Does a reinstall work? You could try doing the cleanup, reboot then a reinstall.

See: Cleanup-Tool — Omniverse Launcher documentation

Thank you for your comment.
I have tried the cleanup tool several times, but I get the above error.

Please let us know if you have the latest Launcher version. To check the version, click the “user” icon at the top right of the Launcher and select “About”. It should be version 1.5.1.

If not, there should be a notification at the “Bell” icon next to the “user” icon for an update. To update, exit the Launcher using the “exit” button in the “user” icon menu. Then run the Omniverse Launcher using the Appimage file.
