PicoBricks/Software/Activities /Dominate the Rhythm line 13 "freq=2000000" doesn't work

[CleanAlibi]

Returns error in Thonny:

Traceback (most recent call last):
File "", line 14, in
File "picobricks.py", line 666, in init
File "picobricks.py", line 592, in init
File "picobricks.py", line 627, in init_display
File "picobricks.py", line 671, in write_cmd
OSError: [Errno 5] EIO

Code works in Picobricks when "freq=2000000" is completely removed.
