Atmel-ice + Mac.Os 10.15 + PlatformIO - No longer working?

Hi, I want to use PlattformIO with Atmel-Ice and my IMac. I#M really sure, that this contalation has worked and I was be able to upload programs over ISP.

I don’t know exacltly what happens, but now my ice device is no longer found.
For test issues, I took the old blink sketch from arduino as an example to upload.
My ini file looks like this:

[env:ATmega328P]
platform = atmelavr
board = ATmega328P
framework = arduino
upload_protocol = atmelice_isp
upload_flags = -e

The board is a arduino uno clone an can be uploaded by usb without atmel-ice. But as I create my own pcb, that is no option.

The error message is the following:

Configuring upload protocol…
AVAILABLE: atmelice_isp
CURRENT: upload_protocol = atmelice_isp
Looking for upload port…
Error: Please specify upload_port for environment or use global --upload-port option.
For some development platforms it can be a USB flash drive (i.e. /media//)
*** [upload] Explicit exit, status 1

I added
upload_port = usb

but that helps nothing.
CURRENT: upload_protocol = atmelice_isp
Looking for upload port…
Use manually specified: usb
*** [upload] could not open port usb: [Errno 2] No such file or directory: ‘usb’

Does anyone has his atmel-ice device running with Mac.OS 10.15 ?

I have the same problem. My error is:
AVAILABLE: atmelice_isp
CURRENT: upload_protocol = atmelice_isp
Looking for upload port…
*** [upload] could not open port ‘usb’: FileNotFoundError(2, ‘Can not find specified file.’, None, 2)
Using manually specified: usb.
My ini file:
[env:ATmega1284P]
platform = atmelavr
board = ATmega1284P
framework = arduino
upload_protocol = atmelice_isp
upload_flags = -e
upload_port = usb
board_build.f_cpu = 20000000L
Everything working perfectly. I could use MicrochipStudio and PlatformIO interchangeably via usb but suddenly I got that error.
Any ideas???
