Cant access Add-ons page in the client

3.5.6 client installed in Linux(Fedora). When I go to the Add-ons page in settings, it flashes, but never shows me anything. I think this may have to do with QT embedded web page or something. Tried reinstalling QT but no go.

If anyone has any solution, thatd be much appreciated! I tried installing some addons manually with no success.

Thanks in advance
