what I've tried:

• doing everything from scratch
• updating all packages
• trying solutions from closed issues

[theoplegends]

quick note that I installed conan thru yay

[badewen]

does your compiler supports c++20?

[theoplegends]

yes cmake 3.28.0 supports c++20
same with my version of gcc

[splexas]

same error, has anyone fixed it yet?
