Actions run failed

When I run action,it always fail and return Actions jobs for this repository have been disabled by GitHub staff. If you are the repository owner, you can contact support via https://github.com/contact for more information. .And my workflow is https://github.com/zzhengzhuo/zisvalidator/blob/d64ff30b76ad3645da1ffbee653074d26134b155/.github/workflows/rust.yml.
I have created a ticket in https://support.github.com/request.But no message reply for one week.
Is there anything wrong?

Unless you have a paid support plan, it can take a while until GitHub staff gets back to you. There are probably hundreds of inquiries every day. Did you use Actions a lot on a free plan, more than what could be considered fair use?
