Headless Build Synergy Issue

Note: I wanted to ask this in the e2 Studio forum, but don't have permissions or something to ask questions there. And the error seems like it may be Synergy related, so maybe this is the right spot anyway.

I recently upgraded our application from SSP 2.2.0 to SSP 2.5.0 and e2 Studio from 2021-10 to 2023-07. Prior to the upgrade, our CI pipeline was successfully able to build using the eclipse headless build module. Post upgrade, our build from within e2 Studio is functioning fine. Our headless build script command is not working:

C:\Renesas\Synergy\e2studio_v2023-07_ssp_v2.5.0\eclipse\e2studioc.exe -nosplash -consolelog -application org.eclipse.cdt.managedbuilder.core.headlessbuild -data %SCRIPTDIR%\DomainDebug -import %BUILDDIR%\Domain -build Domain/Debug >> %SCRIPTDIR%\DebugOut.txt

This is what the log of e2 Studio looks like:

Create.
Opening 'Domain'.
