Describe the bug
Fresh install of CPAI 2.9.5 with only the Coral Object Detection module installed on a Windows 11 PC. Using the Makerfabs Dual TPU PCI adapter and a Coral Dual Edge TPU. Selected YOLOv8 Medium size and started the module. Everything is running fine, and after 30 mins to 1 hour it stops running and shows the following message in the server logs:

objectdetection_coral_adapter.py: F driver/mmio_driver.cc:308] Non-OK-status: interrupt_handler_->Close() status: Internal: Clearing Interrupt event failed: event_id:0 gle=1167

When I try to restart the module, I get the following log:

18:08:15:Module ObjectDetectionCoral has shutdown
18:08:15:objectdetection_coral_adapter.py: has exited

From this point, I can't run the module again until I reboot my PC. Not even restarting the service fixes this (through Services GUI in Windows)

To Reproduce
Steps to reproduce the behavior:

1. Go to Status
2. Click on "Start" in "Object Detection (Coral) 2.4.0"
3. Scroll down to the most recent logs
4. See error: objectdetection_coral_adapter.py: F driver/mmio_driver.cc:308] Non-OK-status: interrupt_handler_->Close() status: Internal: Clearing Interrupt event failed: event_id:0 gle=1167

Expected behavior
The Object Detection (Coral) 2.4.0 module should run with the Dual Edge TPU without issues with YOLOv8 Medium model. If any error is encountered, it should give a more detailed error on what went wrong.
