Upgrading oracle 18.4 to 18.5 Prerequisite check "CheckActiveFilesAndExecutables" failed.

I faced this issue: 
Following executables are active : libclntsh.so.18.1
                                    /oracle/app/product/18.3/lib/libclntsh.so.18.1
                                    /oracle/app/product/18.3/lib/libsqlplus.so

                                  The details are:


                                    Following executables are active :
                                    /grid/app/18.3/lib/libclntsh.so.18.1
                                    /grid/app/18.3/lib/libasmclntsh18.so
                                    /grid/app/18.3/lib/libskgxp18.so
                                    /grid/app/18.3/bin/oracle

Solution:

1- Stop the oracle emagent.

2- Stop the CRS using "crsctl stop crs -f"

3- Re-run the patch using opatchauto resume
