if you connect the camera to a windows computer with a USB cable, you may be able access the storage device even when the camera is not on. move the media file to your laptop and delete it from the camera
If you are completely unable to boot the camera, you can try this to restart the bootloader of the Android OS that runs inside the camera.
Note that I do not work for RICOH and this is not an official RICOH site. If you use the technique below, it may damage your camera. However, I will share what worked for me so that you can access the difficulty and risk yourself.
I had the same problem when I took a 3 hr 16 minute video.
If the camera is not already unlocked, you can unlock it for free.

Once the camera is unlocked, the following command worked for me.
adb shell
reboot bootloader
The process is:
- join partner program (free)
- use free desktop app to unlock camera and put in developer mode
- connect camera to computer with usb
- install adb on computer if you do not have it installed already (adb is an android developer tool which is free)
- run the commands above on the computer.
