The GoPro 12 camera is no longer recognized as a USB mass-storage device after
the first successful connection

STEPS TO REPRODUCE
1. After the system starts, connect the camera via USB cable. Turn it on, after
a while it goes into USB mode
2. Through the Dolphin browser you can see the content of the camera, copy
files or, for example, delete them - everything works properly. You disconnect
the camera/turn it off after the operations are completed.
3. You connect the camera again, turn it on, but this time an error is
immediately displayed:
"The device cannot be accessed. Make sure it is unlocked and tap "Allow" on its
screen flyout. If that doesn't work, then make sure MTP is enabled in its USB
connection settings"

OBSERVED RESULT
No access to files saved on the camera's SD card

EXPECTED RESULT
Access to files stored on the camera's SD card, allowing them to be copied,
renamed, deleted, etc.

SOFTWARE/OS VERSIONS
Windows: 
macOS: 
Linux/KDE Plasma: Kubuntu 23.10, kernel: 6.5.0-26-generic, 
(available in About System)
KDE Plasma Version: 5:144ubuntu2
KDE Frameworks Version: 5.110.0-0ubuntu1
Qt Version: 5.15.10-5  and 6.4.2+dfsg-18 

ADDITIONAL INFORMATION

The only solution to this problem is to restart the system. After restarting
the computer, you can again access the files saved on the SD card.
The problem does not depend on the kernel version - it has been present since
at least November 2023 - I regularly update Kubuntu and run it on current
versions
The problem does not depend on the software version of the GoPro 12 camera -
the problem has existed since the very beginning of its ownership, there have
already been several firmware updates at that time
The GoPro 12 camera does not have any USB connection type setting in its
menu/settings.
