Error: Cannot read properties of undefined (reading 'beforeQueued')

Hi all,
Today I updated ComfyUi and dozens of Custom nodes. After I fixed several issues, there is one left. I can’t run a workflow several times. After a run is finishe, when I try to run it again I get the error message mentioned above and the UI is completely blocked. Re-starting only the UI fixes the problem for one more run. I already read then topic:
ShowText Node, removed it the package completely but the issue persists.

Can anybody help?

Thanks a lot
