App crashes frequently after SDK integration

问题

I've successfully integrated the HERE Flutter SDK into my app. I succeeded to display here maps with markers and to get results from RoutingEngine.calculateCarRoute. Very often, especially when debugging and when navigating back the app crashes since the integration. Here's one stacktrace from a recent crash:

As you can see the crash comes from the Here SDK --> libheresdk.so (here_sdk_library_execute_callbacks+44)

Any idea how to solve the problem? Currently, the SDK is not usable due to these issues. My SDK version is "HERE SDK for Flutter (explore Edition) - Version 4.3.2.0"

UPDATE

My app does the following:

Display the current location on a map
Get Autocomplete Suggestions and a location for a search entry
Get Route Information a.k.a. Directions for current location to chosen destination
Display this route information with a polyline on a map.

I can reproduce this crash by following exactly this flow and by then navigating back from the second map screen to the car route screen.

UPDATE 2:

SDK 4.3.3.0.86 doesn't crash but causes ANR when I do not touch the app and map for a while. When I then force quit the app, I get:

I/appidentifier(14261): Thread[5,tid=14294,WaitingInMainSignalCatcherLoop,Thread*=0x73f03fc800,peer=0x146019a0,"Signal Catcher"]: reacting to signal 3
