Winbox problems with 2.9.43

I just upgraded to RouterOS 2.9.43 and Winbox immediately stopped working. It loads and looks OK, but most of the windows (for example IP → Hotspot → Active) contain no data. If I open a terminal from within Winbox I get an empty terminal window.

However, if I change to using TCP/IP to connect to the router it works.

Has there been some change in 2.9.43 that stops MAC access to Winbox working?

mac is very unstable connection as tcp/ip take care of packet retransmissions end everything (ethernet), and if you use this in secure mode, then even more unstable it becomes.

it is advised to use mac-winbox only if there is no other choice left and you have to connect to device (like there is no IP address present)

The thing is that I’ve found MAC to be reliable, until upgrading to 2.9.43. Is there some reason why it has suddenly stopped working?
