Troubleshooting help wanted - Issue with KNIME SDK

Node Development
1

Hi,
I had a working SDK with KNIME nightly until yesterday. Then, I got weird errors when starting KNIME. I decided to throw away my Eclipse workspace, I checked out releases/SDK from the knime SDK repo, created a fresh Eclipse workspace and set the target platform (complete target) accordingly. (Eclipse and Java versions do fit for KNIME 5.9).
When starting KNIME, the splash screen already looks weird.

Additionally, I get this error message:

CoreSVG has logged an error. Set environment variabe "CORESVG_VERBOSE" to learn more.

I would appreciated any idea how to troubleshoot this problem. I am on MacOS 14.8.2 (23J126) / M2 (got an update yesterday morning…)
