Thanks for reporting this issue and sharing the log.
I can confirm this is a known bug related to the ReadableStream is locked error and Edge process handling during project runs. A fix has been added and will be officially available in our October 1 release.
Please update to the new version once it drops and let us know if you run into any further trouble.
