The install is working fine, it appears to be able to build apps, language server is fine, just the above error appears.

This is a known issue and has since been fixed. Initially reported in #94060. The fix is available on master channel and will be available in the stable channel sometime in the future. It shouldn't disturb your development process.

Closing as this has already been fixed.

Thank you
