Augment LD_LIBRARY_PATH instead of replacing it,
DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
-export LD_LIBRARY_PATH="$DIR/../lib"
+export LD_LIBRARY_PATH="$DIR/../lib:$LD_LIBRARY_PATH"
export SSL_CERT_DIR=$(readlink -m "$DIR/../lib/python3.7/site-packages/certifi")
export SSL_CERT_FILE="$SSL_CERT_DIR/cacert.pem"
