I installed Firegiant Heat Extension, then updated wix to latest version using
dotnet tool install --global wix --version 5.0.0-rc.1
So I changed a Wix MSI Project from version 4.0.4 to 5.0.0-rc.1
<Project Sdk="WixToolset.Sdk/5.0.0-rc.1">
</Project>
But when I reloaded the project, it fail

HeatWave support for WiX v5 is coming very soon.
