Nano RP2040 upload sketch only when forcing the bootloader

Official Hardware Nano Family Nano RP2040 Connect
1

Hi.
After months using nano RP2040, Arduino IDE fails to upload any sketch to my board.
The only way is to manually force the bootloader with a jumper between GND and RESET pins, and then drag the blink.ino.elf.uf2 into RP2040's mass storage device.
But then, if I try to upload a blank sketch get this:

"C:\Users\Pai\AppData\Local\Arduino15\packages\arduino\tools\rp2040tools\1.0.6/rp2040load" -v -D "C:\Users\Pai\AppData\Local\Temp\arduino\sketches\40C31AD8A06EA47F642B5DEC9CD85937/sketch_may21a.ino.elf"
rp2040load 1.0.6 - compiled with go1.16.2
.....................
Failed uploading: uploading error: exit status 1

Arduino IDE version: 2.1.0.

Any idea?

Thanks.

Try factory reset following Nano RP2040 Connect not being detected on USB port

I did that several times.
But after a Factory Reset the only way a I have to upload a sketch is a Hard Reset to show the mass storage device . After that the IDE is able to upload it successfully.

But next time I try to upload the sketch I have to do the same procedure again.
The IDE can not upload neither double tapping the reset button resolves the problem.

thanks.
