Thanks for reporting and using the preview version of PowerShell!
This is a duplicate of #2495. The powershell-7.2.0-preview.6 contains a release note for this:

PSReadLine 2.2.0-beta1 and 2.2.0-beta2 do not work with this preview of PowerShell due to breaking changes in the prediction interface. The upcoming PSReadLine 2.2.0-beta3 release will resolve this. Use PSReadLine 2.1.0 as the temporary workaround.
