It's very common for problems to occur after Windows updates, try uninstalling the updates to see if it works again, but my advice is to migrate to Anyconnect.
Yes, correct but tried to rollback the updates still issue occurs verified every KB no luck.
Delete the current connection and try creating a new one.
Yes, done recreate manually too no luck
Try this VPN client. You can use L2TP.
