access violation reading with refinement after deletion

[veenstrajelmer]

Describe the bug
The code below gives an access violation: OSError: exception: access violation reading 0x00000246736EA038

To Reproduce

import numpy as np
from meshkernel import GeometryList, DeleteMeshOption, ProjectionType, MakeGridParameters, MeshKernel, RefinementType, GriddedSamples, MeshRefinementParameters

lon_min, lon_max, lat_min, lat_max = 99, 114, -7, 13.5
dx = dy = 0.1
crs = 'EPSG:4326'

# create base grid
make_grid_parameters = MakeGridParameters(
    origin_x=lon_min,
    origin_y=lat_min,
    upper_right_x=lon_max,
    upper_right_y=lat_max,
    block_size_x=dx,
    block_size_y=dy,
    )

mk = MeshKernel(projection=ProjectionType.SPHERICAL)
mk.curvilinear_compute_rectangular_grid_on_extension(make_grid_parameters)
mk.curvilinear_convert_to_mesh2d() #convert to ugrid/mesh2d

xx = np.array([98.0, 107.5, 98.0, 98])
yy = np.array([2.5, -7.5, -7.5, 2.5])

delete_pol_geom = GeometryList(x_coordinates=xx, y_coordinates=yy)
mk.mesh2d_delete(geometry_list=delete_pol_geom, 
                        delete_option=DeleteMeshOption.INSIDE_NOT_INTERSECTED,
                        invert_deletion=False)

min_edge_size = 1250 # in meters

lon_np = np.array([lon_min, lon_max])
lat_np = np.array([lat_min, lat_max])
values_np = np.array([-9999, -9999, -9999, -9999])
gridded_samples = GriddedSamples(
    x_coordinates=lon_np,
    y_coordinates=lat_np,
    values=values_np)

#refinement
mesh_refinement_parameters = MeshRefinementParameters(
    min_edge_size=min_edge_size,
    refinement_type=RefinementType.WAVE_COURANT,
    smoothing_iterations=2,
    )

    gridded_samples=gridded_samples,
