Can you open any workflows?
. No: download a fresh 3.7.2, create a new workspace, import previous workflows
. Yes: create a new workspace, try importing failing workflow

Your error message hints at something that has nothing to do with a workflow in particular, but rather KNIME jars that are of mixed versions. What are the ‘couple of extensions’ which you installed?
