No execution in fetching buffer block

[eumel2]

Describe the Issue I can find and start the camera. Wireshark showes packages arriving and the timeout is not triggered either, but code inside the with block is not getting executed

Sample Code

from harvesters.core import Harvester
import numpy as np 

h = Harvester()
h.add_file('/opt/mvIMPACT_Acquire/lib/x86:64/mvGenTLProducer.cti')
h.update()
ia = h.create(0)
ia.start()

with ia.fetch(timeout=3) as buffer:
    print(buffer)
    component = buffer.payload.components[0]
    _1d = component.data
    print('1D: {0}'.format(_1d))

Configuration

• Ubuntu 22.04
• Python: 3.10
• Harvester: 1.4.0
• GenTL Producer: Matrix Vision mvIMPACT
• Camera: Infratec Variocam HD

Actions You Have Taken

There seems to be no hardware issue, the camera can be started and packages are arriving as can be seen in wireshark. Setting Height, Width and PixelFormat doesnt work since i got Read Only access (issue for another day) They are however set to what they should be (768, 1024, 'Mono16') Using Vimba as a GenTL producer does not find the camera at all Timeout in fetch is not triggered
