Conn installation problem

Hi,

I installed everything and tried to run conn by typing in conn in the matlab command line:

I am using a Macbook Pro 2019 with Catalina.
Matlab 2020
SPM version 8

ERROR DESCRIPTION:

Error using conn (line 644)
INSTALLATION PROBLEM. Please re-install SPM and CONN and try again
Error in conn (line 132)
conn initfromgui;
CONN19.c
SPM8 + Beamforming DEM FieldMap MEEGtools
Matlab v.2020a
project: CONNundetermined
spm @ /Users/neurolab/Desktop/Stephan/Programmes/spm8
conn @ /Users/neurolab/Desktop/Stephan/Pipeline/Conn/conn

What can I do?

Best
