Shell Integration error - Unexpected Token '??' in expression or statement

Type: Bug

Just tried to install the shell integration, however when i add: if ($env:TERM_PROGRAM -eq "vscode") { . "$(code --locate-shell-integration-path pwsh)" } to my PowerShell Profile it spits out an error everytime i open vscode.

My shell profile is completely standard apart from the vscode shell integration snippet.

Error looks like this:

At C:\Program Files\Microsoft VS Code\resources\app\out\vs\workbench\contrib\terminal\browser\media\shellIntegration.ps1:39 char:49
+             $CommandLine = $LastHistoryEntry.CommandLine ?? ""
+                                                          ~~
