I upgraded my TPLink VR200 from 19.07.3 to 19.07.4 and looks the same. Everything works as expected 
Btw, MediaTek MT76x0e has been giving error, But not so important It was giving error at old stable one.
One of the guy tries snapshot r14418-d0f295837a and looks good 5 Ghz at this snapshot . MT7610E drive installation to VR200, Deck works
Stable releases comes so frequent. I think It ll come in next 6 month. You know I need Luci
