Why are my Blackfly and Grasshopper3 cameras not detected after restarting MATLAB when I have both the Point Grey and FLIR Spinnaker adaptors installed?

I am trying to connect with the following two cameras in MATLAB: Blackfly S BFS-U3-32S4C and Grasshopper3 GS3-U3-51S5C.

I am using the Image Acquisition toolbox Support Package for Point Grey Hardware to connect with my Grasshopper3 camera, but connecting to my Blackfly camera using the FLIR Spinnaker support by Image Acquisition add-on seem to cause issues.

The FLIR Spinnaker support by Image Acquisition Toolbox add-on includes a file called "Readme.m", which helps setup the FLIR Spinnaker adaptor after all the setup steps have been followed. After executing "Readme.m" at the MATLAB Command Window successfully, I got the following output from executing "imaqhwinfo('mwspinnakerimaq')" at the MATLAB command Window:

>> out = imaqhwinfo('mwspinnakerimaq')

out =

struct with fields:

AdaptorDllName: 'C:\Users\<User>\AppData\Roaming\MathWorks\MATLAB Add-Ons\Toolboxes\FLIR Spinnaker support by Image Acquisition Toolbox\R2021b\mwspinnakerimaq.dll'
AdaptorDllVersion: '6.5 (R2021b)'
AdaptorName: 'mwspinnakerimaq'
DeviceIDs: {[1] [2]}
DeviceInfo: [1×2 struct]

<User> is just a placeholder for the user under which the FLIR Spinnaker Support for Image Acquisition Toolbox add-on was installed. 

As you can see, both of my cameras are present in the "DeviceIDs" property of the output struct, so I could potentially use this adaptor for both of my cameras. The main issue is that when I try to use my cameras through the FLIR Spinnaker adaptor using any format, I receive the following error:

 

ERROR: Error using iatbrowser.HardwareTree/hardwareTreeNodeSelectedCallback


Error in iatbrowser.HardwareTree/initialize 
Warning: Error occurred while evaluating listener callback.

Furthermore, when I restart MATLAB, my cameras no longer appear under the FLIR Spinnaker adaptor. Only my Grasshopper3 camera appears under my Point Grey adaptor. The following code snippet is the output of executing "imaqhwinfo" at the MATLAB Command Window after restarting MATLAB:

 

>> imaqhwinfo

ans = 

  struct with fields:

    InstalledAdaptors: {'gentl'  'gige'  'mwspinnakerimaq'  'pointgrey'}

          ToolboxName: 'Image Acquisition Toolbox'
       ToolboxVersion: '6.5 (R2021b)'

How do I resolve this issue so that I can use I can use the FLIR Spinnaker adaptor?

When multiple adaptors are installed, it is possible that they can interfere with each other. This means that if one adaptor accesses a camera, other adaptors may not be able to interface or identify that other camera.

In this case, it is highly likely that the Point Grey and FLIR Spinnaker adaptors are interfering with each other, since they are trying to access the same hardware. You should be able to use both of your cameras with the FLIR Spinnaker adaptor, if you uninstall the Point Grey Support Package for Image Acquisition Toolbox. Please refer to the following documentation for steps on how to uninstall a support package:
