Software & Updates a blank opening screen ubuntu 20.04LTS

[flaggman]

I tried to install Brave browser but the ppa's were earlier than 20.04 vers and install did not work. Removed ppas related to Brave and after that Software & Updates program only opens a blank screen. Tried reinstalling using synaptic but that did not fix the problem. Could use a few tips.
Thanks

You dragged and dropped an image into the message editor. That will not work. Instead, go to the advanced message editor by clicking on the "Go Advanced " button, and upload your image using the paperclip icon in the message editor toolbar, or the "manage attachments" button below the advanced message editor.
