There are three possibilities that occur to me: the first is that you have not installed OpenOffice correctly, the second is that you have a bad download, the third is that you have not downloaded the correct version for Mac Catalina.
I am not a Mac user, so can not help further with your problem.
Apache OpenOffice 4.1.8 on Xubuntu 20.04.1 (mostly 64 bit version) and very infrequently on Win2K/XP
