Exporting pool(s) on TrueNAS 12.0-RELEASE

I get the below errors on the console when attempting to export any pool on TrueNAS 12.0. This is with pools created on FreeNAS 11.3 and on TrueNAS 12.0. They are all encrypted pools (2 legacy GELI, and 1 ZFS native). Please let me know if I can provide any logs.

The steps I took:

1. Go to Storage > Pools
2. Click "Pool Operations"
3. Click "Export/Disconnect"

Once that happens a spinning blue circle appears, after a few minutes the below errors start appearing on the console (hundreds of them). After the errors stop the normal export window loads as expected, after I confirm export and click "Export/Disconnect" the export hangs on %20 while the same errors start generating again. I currently cannot export pools.
