Frames are moving around on their own in TB Harmony Advanced 17

I’ve begun to experience an issue with my program. When I open my file, a few minutes in the frames will start to chance exposure rate to 1s and the frames from the beginning of the timeline will suddenly shift to the end or where my marker currently is. This happens even when I am not using my mouse, pen, or are typing. I have Windows 10 OS which just recently updated, I have a Huion Kamvas 13 (winTab support unchecked in my TB preferences), and the most updated version of Toon Boom Harmony Advanced 17. Has anyone else experienced this before? I recently uninstalled and reinstalled both my tablet and the program, so if the error persists I will try to upload a screen capture. I apologize for the vague description, I’m not sure how else to describe it.

Thank you for any help you can offer.

SOLVED: A hotkey on my tablet was stuck
