21.3 version possibly incompatible with VeriStand 2019

[jtcalvert]

Describe the bug
After upgraded the SEEC CD to version 21.3 to get support for the 9226 module, I get the following error during deployment in VeriStand 2019 R2:

VeriStand Connection Error

Project Window.lvlib:Project Window.vi >> Project Window.lvlib:Command Loop.vi >> Project Window.lvlib:Connect to System.vi

=========================

Error 1003 occurred at Project Window.lvlib:Project Window.vi >> Project Window.lvlib:Command Loop.vi >> Project Window.lvlib:Connect to System.vi

Possible reason(s):

LabVIEW: (Hex 0x3EB) The VI is not executable. This error may occur because the VI is either broken or contains a subVI that LabVIEW cannot locate. Select File>>Open to open the VI and verify that you can run it.

To Reproduce
Steps to reproduce the behavior:

1. Start with normal installation of VeriStand 2019 R2 with the custom devices installed.
2. Download and run the 21.3 release for VeriStand 2019: ni-scan-engine-veristand-2019-support_21.3.0.6_windows_x64.nipkg
3. Try deploying a project that uses the SEEC CD to a RT target.

Expected behavior
Project should deploy and run without error.

Desktop (please complete the following information):

• Host OS: Windows 10
• SW on target:
• VeriStand 2019 R2
• NI Scan Engine 8.0
• NI-Industrial Communications for EtherCAT 19.0
• I/O Variable Remote Configuration Web Service 19.0

Workaround
Uninstalling the 21.3 version of the custom device and installing 20.2 instead works as expected.
