Simulator preview not loading -- don't understand error

Preview logs from diagnostics report attached:

I couldn't figure out how to upload the entire diagnostics folder.

Hi,

Sorry to hear you are having problems getting previews working. The diagnostics in the attached file is not enough for us to diagnose the issue, sothe best next step will be to file a feedback with the full diagnostics so we can take a look.

Steps to generate helpful diagnostics:

  1. Download and install the logging profile on all devices involved. Instructions and profiles are available here: https://developer.apple.com/bug-reporting/profiles-and-logs/?name=swift
  2. Reproduce the issue
  3. Click the "Diagnostics" button in the error banner in Previews' Canvas area (or if the banner is missing you can use the menu: Editor > Canvas > Diagnostics)
  4. In the sheet that appears, click "Generate Report" in the bottom left of the sheet
  5. Attach (or make from the folder) the resulting zip file to the bug (will be named something like previews-diagnostics-0123456789.zip)
  6. Generate the sysdiagnose(s) and attach those too
