No problems at my end, but several people are apparently still having issues with kwallet, among which the crashing of the ksecretd daemon. 
- Plasma 6: KWallet hangs and Dolphin SFTP fails — missing Secret Service backend?
- Turning on laptop goes through Manjaro boot settings screen twice for no reason
- Kwallet now asks for password on login (since latest update)
(Yes, that second thread above also mentions kwallet issues.)
