Arduino IDE wont upload and freezes

Development Tools IDE 1.x
1

Hello Friendly People,

since about an hour ago, i have encountered a new problem working with my Nano RP2040 Connect:

When I try to upload code it compiles as usual but then the IDE just freezes while the upload is in progress. When this happens, the green progress bar overshoots (see pic 1) and nothing happens.

I can not open/close/save any sketch using the IDE and it only resolves once i disconnect the arduino. I have no idea whats happening or what could have resulted in that behavior. I tried to disconnect and restart everything, but it didn't change anything.
Pls help.

EDIT: Also the window, which normally shows once a sketch is uploaded to the RP2040 doesn't show and the "upload" progress bar is nonexistant. I think it has something to do tih the fact that there are less COM-Ports visible then usual, only COM 1 and COM 5 (RP2040 is connected to 5).

Kindest Regards
Lennart

Have you tried what Datasheet recommends?

All Arduino boards have a built-in bootloader which allows flashing the board via USB. In case a sketch locks up the processor and the board is not reachable anymore via USB it is possible to enter bootloader mode by double-tapping the reset button right after power up.
