OR-TOOLS EXCEPTION_ACCESS_VIOLATION when running TSP

When I run the TSP algorithm I get a fatal error on the native or-tools library. There is a small chance to execute the TSP algo with success when running it only one time, but for consecutive executions without a big interval between them, it always happens.

I'm currently running it on Windows 10, but it tested it on Debian and Alpine and the problem still happens.

Here is a preview, but you can see the full log here (each time I get this error the problematic frame is different).

Java code:

public List<AlgoNode> solve(final Collection<AlgoNode> nodes, final AlgoNode start) {
     if (nodes == null || nodes.isEmpty())
         return new ArrayList<>();
     if (nodes.size() == 1)
         return new ArrayList<>(nodes);

     // Setup Variables
     var list = new ArrayList<>(nodes);
     var depot = start == null ? 0 : list.indexOf(start);
     var manager = new RoutingIndexManager(list.size(), 1, depot);
     var routing = new RoutingModel(manager);

     // Define dummy weight function
     var transitCallbackIndex = routing.registerTransitCallback((fromIndex, toIndex) -> 1L);
     routing.setArcCostEvaluatorOfAllVehicles(transitCallbackIndex);

     // Solve
     var parameters = main.defaultRoutingSearchParameters().toBuilder();
     parameters.setFirstSolutionStrategy(FirstSolutionStrategy.Value.PATH_CHEAPEST_ARC);
     var solution = routing.solveWithParameters(parameters.build()); // Problematic line
     return new ArrayList<>(); // Dummy return
 }

I also tryied making the method syncronized, using a lock and calling closeModel() after running the TSP, but no lucky.
