May be you can update g++?
It work well on my machine

[Legit4K]

g++ (Ubuntu 7.4.0-1ubuntu1~18.04.1) 7.4.0�������

Is this version compatible?

You may need to run
apt update && apt upgrade

[Legit4K]

It didn't seem to update but I managed to add the toolchain PPA and switched to g++ 9 & gcc 9 and now it works, thanks!
