Exchange Server

Visitor

I'm a C# developer and I'm working on App for Exchange Server to backup and restore Mailboxes.

My application was working good till last week. I ran the windows update then my app stopped working completely.

 

I'm getting below the Error while retrieving mailboxes:

 

Error: The syntax is not supported by this runspace. This can occur if the runspace is in no-language mode.

 

I checked the forum and it says the error because of the "April 2021 security updates"

 

Do I need to make any code change or machine level configuration changes?

 

Please help me

 

Thanks in advance
