WSE 2016 VM - Windows Search problems

Hi all - 

Brand new Windows Server Essentials 2016 VM on Server 2019 Hyper-V, brand new Dell T340 - all SSD storage, very nice.

Windows Search is crapping out. Indexing about 600,000 items on two volumes, it works for a minute, and then searches return an unclickable list of files with white generic icons and no data. Restarting the service works for a while. I've reindexed a bunch.

Any thoughts or ideas? Thanks!
