OpenCPN crashes on GPS

[nebosa]

After scrapping my Moitessier I need a new solution.

I use this USB GPS mouse:

Navilock Products 62532 Navilock NL-8022MU USB 2.0 Multi GNSS Receiver u-blox 8 4.5 m

Shortly after OpenCPN gets the GPS signal, the program crashes.

After the start I see the active GPS connection in the upper right corner and how many satellites in the dashboard

just received.

After a short while, more precisely at the moment when my boat icon on the map turns red and the bearing line

appears opencpn crashes

With a "normal" USB-GPS mouse everything runs normally.

Only OpenCPN is affected, SignalK delivers the GPS data, avnav can also receive and process this GPS data.

When I restart opencpn exactly the same thing happens again

What I noticed is:

I set up GPS using Openplotter's Serial app:

The "normal" USB mouse is the device ttyUSB0

the navilock is ttyACM0

I think I tried everything, baud rate from 4800 to 38000 115000

Set up as NMEA 0183, connected to SignalK or GPSD always the same OpenCPN crashes

Opencpn gets the data via SignalK / localhost 3000.
If I set up a TCP connection tcp/ localhost/ 10110 and disable the SignalK connection, does everything work?

Does somebody has any idea ?

Just a guess. The data sheets is noting an update frequencu of 18Hz. That is 18x fater then an ordinary gps. So likely O is getting to much info, to fast and the new position is coming in before the previous one was compled.
