KNIME workflow won't import

I have a KNIME workflow that I used to use, but not for while since I changed PC and on the new one I now use KNIME 5.3.

The problem I am having that when I try to open (double click) or import the workflow nothing happens no error, no notification, it just does not work.

This is the workflow:

LoadMolPortData_v2_example.knwf

It was made several years ago, probably version 3.7.

Does anybody know what can be done to fix the workflow so I can open it?

P.s. I can not have 2 versions of KNIME on my PC installed at the same time, so I can’t view the old version to replicate it manually in KNIME 5.3.

P.p.s. I am running KNIME 5.3 on windows 11
