One more time. Going to copy/paste the steps I wrote down for myself on how I finally got this to work after two days of trying.
----
I'm going write it all out again in case we ever need to look back on it.
I did a dozen other things but I think these are the repeatable steps to fix.
Issue: After syncing and closing a workshared cloud model and shutting down Revit 2023, the next morning I was unable to open that file on 2 different computers that worked the day before. Nobody else had accessed the file on either day. Another cloud workshared model belonging to the same project would not open. Throughout the entire process and all of the testing, Revit would lock up at the exact same spot. Screenshot below is from a forum post from another person, with the same issue, locked up at the same spot.
Potential cause: I have two fairly large Design Options in the model, one for a central plant and another for an area of a building. Before syncing and closing I changed both design options from secondary to primary via the "Make Primary" button in the Design Options window. After that, I Accepted Primary on one of the options. I don't think I did much else in the model after that before syncing, exporting an NWC, and closing for the night. Other than this, nothing I did was abnormal or outside of my normal workflow and there were no errors or issues or network problems or anything else at the time.
Another potential cause: It seems that Addon's were also somehow (or fully) related. Both machines had a different set of addon's, but the identical ones were eVolve Mechanical, the NWC Exporters, and the Autodesk addons needed for workshared cloud models. My main work PC also had DiRoots One, pyRevit, and an Alignment addon installed.
Steps I used to solve:
- From Autodesk Desktop Connector tray icon, click Select Projects and unselect all projects.
- Clear the potentially corrupt/damaged cloud workshared model following Autodesk's guide: https://www.autodesk.com/support/technical/article/caas/sfdcarticles/sfdcarticles/Clear-a-corrupt-da...
- Disable addins following Autodesk's guide here: https://www.autodesk.com/support/technical/article/caas/sfdcarticles/sfdcarticles/How-to-Disable-Add...
- The easiest way is to just rename the 2023 folder to 2023x or something, so it still exists with everything in tact.
- This guide has a note that says to leave three files for Cloud models (Autodesk.Collaborate.addin, ExportViewSelectorApp.addin, and the ExportViewSelectorAddin directory). These files must be removed despite what the help topic says, so the Addins folder is completely empty. Leaving those 3 files in still causes the lockup.
- Possible step: I think at this point on both machines, I re-added the project through the Autodesk Desktop Connector tray icon, but I don't remember.
- Open Revit 2023 and through the Autodesk Docs explorer on the left menu, navigate to the directory containing your model. Click the three dots on the far right to expand the menu and click Version History.
- Open a file from the day before, prior to the Design Options being Primary/Accepted, and Open and Audit'ed it.
- It will open with a bunch of errors. Press whatever you need to continue through and finish opening the model.
- Once your model is open, File -> Save As and save it to another location. On one machine I used the project folder that was on the cloud and on my other machine I saved it to the C drive.
- Close Revit. Don't Save or Sync.
- Reopen Revit and open the file you just Save As'd via the Models:Open... dialogue. Same thing, press OK until it's open. Close Revit. Don't Save or Sync. (Steps 9 and 10 probably aren't needed but I wanted to doublecheck every step of the way)
- Go back to the directory in Step 3 where you disabled the addins, and rename it back from 2023x to 2023.
- Reopen Revit and the file you Save As'd using the Models:Open... dialogue. It should now load with all of your addins enabled. Close Revit again. Don't Save or Sync.
- Reopen Revit and navigate to your live workshared cloud model via the Autodesk Docs browser and open your real model
- Problem solved?
With steps 5-13, on one PC, it worked the first time I did this. On the second PC I was fixing, I had to do it five or six times to get it to open. I was probably screwing up something else along the way but it might take a few tries or opening a few different versions in 6.
Things that didn't seem to help at all: Updating Revit (I was one hotfix behind). Updating ADC (one version behind), opening the live model with worksets closed, opening the live model with auditing, clearing temp folders, rebooting a million times
