NextionDriver not running

[PE1DON]

The question must have been asked before but I can't figure it out.
I recently upgraded my Pi-Star (3B) to 4.1.8 and since then, my Nextion screen has been only partially working. I have tried all sorts of things but it points to the NextionDriver
I am using an MMDVM Dual Hat modem and my Nextion screen is connected to it.
I see the information coming up on the screen but after a while, the RX and TX information is no longer displayed.

When I do a fresh install with 4.1.5 it seems to be fine for a while. But after a while it didn't show the information. The MMDVVM hat is upgraded to firmware 1.6.1.
If I then log in with PUTTY and I follow the steps of installing the NextionDriver, the last step is
sudo NextionDriverInstaller/check_installation.sh

the NextionDirver is not working.

I have similar problems. went into ssh and executed sudo systemctl start nextiondriver.
Still missing t30 en t32 which are the frequencies and some other fields, but station data is coming up.

Did not fix it totally. Had to modify the first [Nextion] section in mmdvmhost and changed the port there.

[Nextion]
#Port=modem
Port=/dev/ttyNextionDriver
Brightness=50
DisplayClock=1
UTC=0
ScreenLayout=4
IdleBrightness=20

Now I have more info but still not all.
see the picture....
