This is a new known issue, filed here. A bug has been discovered that corrupts PAT files from previous versions when opening in 1.10.0. Until this issue is resolved, please do not open PAT projects created in previous versions of OpenStudio with PAT 1.10.0. Creating new PAT projects in 1.10.0 is fine.

This is a serious issue, and the team is actively working on a bug fix release of 1.10.0. Stay tuned.
