MacBook Pro 13”, macOS 10.15
Boot into Safe Mode (Use Safe Mode to isolate issues with your Mac and Playing Safe: what does Safe Mode do?) and try unzipping from there. Then reboot normally.
NOTE: Safe Mode boot can take up to 10 minutes as it's doing some system cache cleaning, volume verifying and directory repairing.
That error could be caused by damaged system files in the upgrade process. Try downloading and applying the macOS Catalina 10.15.3 Combo Update and then try again.
Thanks for your reply:) I will try it!
cannot unzip the file with "error 79 - Inappropriate file type or format."
