On my 11.5.1, the installer 1.2.0 denied even the SIP disabled.
Also, terminal is not working as follows.
/usr/sbin/spctl kext-consent list
spctl: no kext consent configuration found
/usr/sbin/spctl kext-consent add 5RHFAZ9D4P
spctl: failed to store new configuration.
Please advise me if you have any good ideas. Thanks!
