P1S is connected but will not print files

Hello,
My P1S is connected to bambu studio, I can control it from the dashboard, light, movements etc no problem.

But when I send a print to the printer, it shows as downloading, tells me the printer is busy and brings up the camera, then nothing happens. The dashboard just shows the printer with no print files loaded.

It was working fine earlier today.

The SD card may be having issues. Try using a different one.

Done, thank you.
Id actually taken the factory SD card and removed all my time lapses and models to free up space.

Installed a freshly formatted 32gb cards and works fine now.
Thanks again.

Had the same issue, formatting the SD inside the machine and then retried and it started working again.
