I got a panic during a `pulumi up`: the GitHub workflow has finished correctly (reporting failure 👍 ) but the Pulumi app thinks it's still in progress. And

pulumi cancel

is producing bad mojo:

4:10 $ pulumi cancel
This will irreversibly cancel the currently running update for 'dev'!
Please confirm that this is what you'd like to do by typing ("dev"): dev
warning: A new version of Pulumi is available. To upgrade from version '3.34.0' to '3.37.1', visit <https://pulumi.com/docs/reference/install/> for manual instructions and release notes.
error: [409] Conflict: The Update has already timed out
14:10 $ pulumi stack ls
NAME              LAST UPDATE  RESOURCE COUNT  URL
myorg/dev*        in progress  9               ...

Any suggestions on how to really really cancel this? And maybe some hints on where to start looking for errors like this:

stderr: panic: fatal: An assertion has failed: cannot read an archive that has no contents
