First, you need at least 12.5GB of free space.

Try again while in Safe Mode.

Hmmm. You need to uninstall CleanMyMac & F-Secure. You only have 13.89GB free space, not 23GBs. You only have 4GB RAM which is the bare minimum to run Catalina much less all the software you have installed. Get rid of the first two problems and test again. You didn't allow Full Disk Access as mentioned.


Hopefully CleanMyMac didn't screw up your Mac too badly.
