Thank you for letting us know! With a little more info, we should be able to reproduce this issue and get it resolved.

  1. Have you installed desktop previously, or was this a fresh install?
  2. Could you please upload the log files? There is some extra info on app startup there. Either here or to hello@comfy.org works.

Have reviewed the logs - it is almost certainly being caused by a custom nodes.

If you search for the exact string [info] ERROR: Restoring in the main.log you sent, you should find 4 instances - each one naming an extension that failed to be restored.

There were some other errors, but this is the easiest starting point. You can simply disable those four by moving their directories out of the custom_nodes directory in your install location.
