WinSCP generate HTTP URL error

Hello!
Since SRP policy started on PC can't generate HTTP rural, getting an error:

C:\Program Files (x86)\WinSCP\Extensions\GenerateHttpUrl.WinSCPextension.ps1 : Cannot dot-source this command because it was defined in a different language mode. To invoke this command without importing its contents, omit the '.' operator.
+ CategoryInfo : InvalidOperation: (:) [GenerateHttpUrl.WinSCPextension.ps1], NotSupportedException
+ FullyQualifiedErrorId : DotSourceNotSupported,GenerateHttpUrl.WinSCPextension.ps1

On SRP logs don't see anything was restricted.
Can you maybe help how to figure how to fix it?
SRP not blocking .ps1, you can run regular .ps1 script manually.

I do not understand the error. There's no . operator.

Anyway, can you reproduce the error when executing the script manually?
To get the command to execute the script, you can press Shift+Ctrl while submitting the extension options dialog:

Yes, I do get the same error if I do it manually.

I've never seen this problem before. From the little information on the error message I've found online, it seems that your system some restrictions on executing PowerShell scripts. It somehow connected to AppLocker and PowerShell Constrained Language Mode:

I'm afraid there's not much we can do about it on our side.

You might be able to get the WinSCP PowerShell scripts whitelisted.
