Fails to send print to H2D

I've had my H2D for awhile now. Recently I cannot "send" the print to the USB on the printer. It goes to 15% and says "failed to send, please try again"

I can start a print through Bambu Studio no problem, works every time. But sometimes I need to send to USB flash drive and start print remotely the next day and I can't do that because it fails to send the file.

Things I've tried: -Restarted printer -Logged out of cloud on printer, Bambu Studio on computer and mobile -Reformated USB flash drive -Tried different flash drive -Tried sending over LAN only mode -Reset router -Forgot WiFi network and re-connected

Nothing has worked! Has anyone dealt with this and figured out how to fix it?
