Cannot Start Application

I am seeing this an error today that I had once before, quite a while ago during an attempted update.

TROUBLESHOOTING

  • After deleting the ClickOnce cache, the error persists. I tried this twice, emptied trash, rebooted. No resolution.

  • Uninstalled Plumsail Designer, installed latest version. Same error.

  • Tried another device, on another network. Same issue.

CLOUDFLARE? ( I know the outage illustrated is a few days old but wondered if it was still impacting some users)

Below is a summary of the errors, details of these errors are listed later in the log.
