RDM crashes when trying to view properties or add new item

Hi all,

I am running RDM free 2020.2.17.0 64bit and I am having an issue where when I want to open up the properties of a connection, or want to add a new item where it needs to open a new properties window, RDM GUI freezes up immediately. No errors given, no Not Responding either on the GUI or in the processes, it just locks up. Right click on the taskbar icon and than choosing close window doesn't work, I have to kill RDM via Taskmanager.

I am running W10 , version 2004 buildnr. 19041.508

Has anyone else experienced this?
