When running on Windows 1809 (not joined to domain or AAD):
Get-AADIntAccessTokenForAADJoin -SaveToCache
I receive following error:

Are you running the command in PowerShell or ISE? VS Code is currently not supported for interactive logon.
If you don't use MFA, you can save credentials to a variable and then get the accesstoken.
$Cred = Get-Credential
Get-AADIntAccessTokenForAADJoin -SaveToCache -Credentials $Cred

[pawp81]

I am running it in PowerShell.
Yes I am using PowerShell so the option -Credentials parameter didn't work:

[NestoriSyynimaa]

Do you have any error reports for the non-working Get-AADIntAccessTokenForAADJoin -SaveToCache -Credentials $Cred?

Okay, seems that your organisation requires MFA so the credentials wont work. Back to the original issue then.
You are probably using a quite recent Windows 10, which is missing a registry key HKCU:\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION

As a workaround, you can create the missing registry key and add the value of 0x00002af9 for powershell.exe and powershell_ise.exe as illustrated below. After that, start a new PS session and the original command should work.

I'll fix this issue for the next release.

I have same issue unfortunately, I checked and already had those reg keys.

[NestoriSyynimaa]

Are you also trying to use saved credentials and MFA is required? Any error messages?

[Kav7]

I tried with an account that doesnt have MFA and after entering the password in the popup box, it just goes blank white, I eventually close it which causes this error:

Could not get OAuthInfo!

Another bug due to recent changes :(
Try to comment out the line 1322 in AccessToken_utils.ps1 and remove and import module:
# $web.ScriptErrorsSuppressed = $True

[Kav7]

That worked! Very nice :)
