Library Validation: mapped file has no cdhash (in Mac OS X Catalina 10.15.1)

I'm getting this error when trying to activate the add-on on my Mac OS X kodi... the relevant part of the kodi.log is this:

NOTICE: ADDON: xbmc.webinterface v1.0.0 installed

Is there any workaround to deal with this issue?

In my opinion, it is a new feature of osx 10.15 which requires signed binary.
you could googling to disable it.

Thank you Janbar,
You're indeed correct!.. it's a notarization problem since the shared library is not notarized... it's not straightforward to solve given that the kodi binary (the release version) is in fact signed, contrary to the pvr.mythtv.5.10.15.dylib object...
The proper way to solve it is through a "synchronization" between the teams compiling kodi and the plugin (or both use notarization or none uses it, ... today there is a mismatch; or the other option is to use an entitlement in kodi's building process, basically saying "do not check for notarization in the libraries used")...

The workaround that I found that might be useful for others with this problem is to use not the kodi release version but one of the nightly build (that are not using notarization) than can be found here:
