I can confirm same issue happens on my Arch install: Wayland + Plasma 5.24.5. 
Krfb outputs no errors. KRDC shows: 'KRDC: rfbInitClient failed' then launched in terminal apart from  'Autentication failure' message in GUI.

@trakno@hotmail.com, have you been able to solve problem?

I can confirm I am getting this as well, I think it is related to bug 451086 as I am getting both.
