Serial can't find my devices

[pacman]

I am interested to OP3 because it has the 64 bit OS, so it has no sense for me to try the 32 bit version.

I executed the requested steps and the result is:

wrong external apps format: unexpected EOF while parsing (<string>, line 0)
No module named 'openplotterMoitessier'
No module named 'openplotterMacarthur'
No module named 'openplotterOpenmarinebox'
No module named 'openplotterMaiana'
No module named 'openplotterSdrVhf'
No module named 'openplotterIot'
No module named 'openplotterNotifications'
No module named 'openplotterGpio'
No module named 'openplotterI2c'
No module named 'openplotterPypilot'
No module named 'openplotterAvnav'
No module named 'openplotterNetwork.serialPorts'
No module named 'openplotterDashboards.serialPorts'

as soon the command completed, inside the Serial GUI the connected devices showed up.
Looking forward to hearing from you.
Thanks
