ocijdbc18.dll Can't Load 32-bit DLL On AMD 64-bit Platform

For ODBC and other tools both 32 and 64 bit Oracle Client are needed. It seems, that 64bit SQL Developer 20.4.0 ignores Oracle Client settings and search for ocijdbc18.dll in the path instead. So it finds 32 bit version first, when we want to use OCI and gives this error. But it should use the 64 bit version.
