Vernalis Ertl Scaffold Keys Node crashes

Dear all,

I just tried to use the Ertl Scaffold Keys node for the first time today, inputting a list of 585 substances (as SMILES), and the node simply crashes (i.e. KNIME completely crashes) without warning after ca. 8% of execution (very reproducible).

I am currently running KNIME 5.4.3 with Vernalis Version Vernalis Research, UK Vernalis Core-extension for KNIME Workbench 1.38.0.v202503121017

OS is Win 11 24H2.

Any idea what might be going on?

Thanks

Joachim
