Weird messages Arduino Nano 33 BLE

Hi! I'm currently making an test-project where i'm connecting my Arduino Nano33 BLE to my iPhone. All worked fine, but until yesterday, i get this weird message while compiling... I didn't change anything, and the Arduino compiles without problems, but it gives me this big message... Does anyone have an idea? I'm on an mac, btw.

These are just warnings and I had no issues with them so far. I just ignore them. My compiler states I use version 2.4.1 of the board support and the messages are almost identical to your messages. Slightly different order.

Can you program your sketch to your Arduino? Do you have any BLE issues?
