@Venkata Gadepalli and @Stephane Tailland suggested that there might be an issue with the validity of the application signature. This could make sense, given the following line in the error I am getting.
Termination Reason: CODESIGNING 1 Taskgated Invalid Signature
They suggested to run the following command, which turn out to completely resolve this issue!
user@machine name % codesign --verify --deep --strict --verbose=2 /Applications/SoftwareAG/*/Eclipse.app
/Applications/SoftwareAG/Designer/Eclipse.app: invalid Info.plist (plist or signature have been modified)
In architecture: x86_64
user@machine name % sudo xattr -r -d com.apple.quarantine /Applications/SoftwareAG/*/Eclipse.app

user@machine name % sudo codesign --force --deep --sign - /Applications/SoftwareAG/*/Eclipse.app
/Applications/SoftwareAG/Designer/Eclipse.app: replacing existing signature
