Error Processing Video "Failed to get image from video device"

[EverydayPancake]

Hi there, there seems to be a problem with SMM2OCR, as it is not working.
I am currently using OBS 29.1.3, obs-virtualcam 3.1.0, MarioMaker2OCR_1.0.73.However, a pop up message shows "Failed to get image from video device". Is there any way to fix this? Thanks in advance.
