Endnote runs extremely slow in Catalina

Hi,

I have seen a few posts already about this and contact the tech support but the issues is still unresolved.

I have a new macbook pro that runs the latest version of Catalina (10.15.3) and I purchased the latest version of Endnote and updated it to the most recent version (X9.3.3). Despite this, after a few hours of using the endnote (any library stored on my hard drive) it slows down to a halt and becomes essentially useless as I would takes several minutes to just click on a reference in the library.

Clearly this is a major problem and I am not the only one experiencing it
