Nano 33 BLE not connecting to computer or advertising

My Nano33 BLE was working fine an hour ago. I uploaded a sketch to it yesterday. When I tried uploading a sketch to it again (an hour ago) it seemed to break. The computer could not discover the arduino in ports, i.e. when I tried plugging it into the computer and loading a sketch, it threw the following errors:

No device found on cu.usbmodem2301
Failed uploading: uploading error: exit status 1

I then plugged and unplugged everything, restarted the Arduino IDE and computer, etc. for a couple minutes - didn't work.

I then tried the iphone app that connected with it before problems started happening and the app would not connect.

The arduino usually advertises the name "Arduino". However, I can't find "Arduino" anymore when looking for advertising bluetooth devices.

I did have my arduino nano wired to another arduino. Perhaps I burned the nano when I plugged both arduinos into the computer at the same time. How would I troubleshoot that? The nano powers up (green light) when I plug it in (it just isn't discoverable when I plug it into the computer).

Any help would be greatly appreciated!

Solved! I went into bootloader mode and that for some reason allowed the arduino to connect to the computer... not sure why - but it worked! I figured there was something wrong with the old sketch that cause a connection issue.
