Can't launch DaVinci Resolve 15 on Ubuntu 18.04

Hi,
Today I installed DaVinci Resolve 15 on Ubuntu 18.04, and the first time I launched it it opened up and I was able to see the software overview and to set the preferences, but then I clicked "start" and nothing happened. Now when I try to launch the software just nothing happens. Can someone help me?

check the program location.

so my case is...

"/opt/resolve/bin/resolve"

run this binary.
