It looks like too old compiler. Which compiler version do you have? Can you update it to the newer/latest version?

[Zombie-Ryushu]

I'm using gcc due to update alternatives.

I'm building it on GCC 9.4.0 and 11.4.0 in GitHub Actions, and works good on both of them. But I have no experience with OpenSuse. Hard to tell what's wrong there. Conversion to std::optional should be valid operation and works on all platforms that are used on GitHub Actions.

[Zombie-Ryushu]

I will have to check it on OpenSuse Build service.
