Error received during OTA: Unknown error

I'm working with an Arduino NANO NP2040 Connect. I've created things, variables, dashboards, etc. The sketches compile and download fine for a couple of days. Today, the OTA fails with Unknown error.

When I tried to connect via USB and my computer, the upload fails as well.

Need advice.

Hi @parttimehacker did you already tryed to put the board in bootloader mode and try upload via USB?
