Comment (by mklengel):

 For testing I tried the following and it seems to be a workaround.
 The building process is running and later on I will activate py37-sip4
 again.

 Note: It is not recommended to uninstall/deactivate a port that has
 dependents as it breaks the dependents.
 The following ports will break: py37-pyqt5 @5.15.4_1
 Continue? [y/N]: y
