Check the Orchestrator server and try to find out if there is enough free space available on the C drive. Perform some cleanup in order to free some space. After the cleanup, try to publish again.
Possible next steps to mitigate and also avoid this issue:
clean up more space on the C drive
increase the C drive disk
move the Orchestrator storage for packages and libraries to another disk
monitor the Orchestrator and SQL server resource usage in order to avoid issues like this.
For the Orchestrator storage location, please see below documentation link.
