Teams install failing on Server 2019. Is there a fix?

I'm trying to install Teams on a Windows Server 2019 terminal server. After reinstalling, Explorer crashes when Teams starts. Could this be related to Teams support being deprecated on Server 2019, or is there something else worth checking?

Try repairing Microsoft Edge WebView2, then test Teams again. That resolved a similar startup problem after a second reinstall, though it doesn't establish that every Explorer crash has the same cause.

For a longer-term fix, look at moving the remote desktop hosts to a newer Windows Server release. Server 2019 is out of mainstream support, and Teams support changes make it a shaky choice for a new deployment. Check the current Teams and remote desktop support requirements before picking the target version.

Sideloading may be worth testing if you're stuck on 2019. An earlier version of the new Teams installer reportedly needed sideloading enabled through developer options on that OS. No guarantee it still works, so I'd try it on a test server first.

If only a few people need Teams, separate laptops could be a practical workaround while you sort out the server. Not ideal for everyone, but it takes the terminal server out of the Teams setup without holding up those users.
