Describe the bug well at first running the Linux Binary via terminal yeilds a dotnet 3.1 error for this you need to first make sure yay is built on your system most arch distros have yay but vanilla arch doesn't on vanilla arch input the commands as followed

1. sudo pacman -S base-devel and make sure git is installed too next go to your downloads folder in terminal 2)type git clone https://aur.archlinux.org/yay.git&&cd yay 3)makepkg -si (will build yay and install it) part 2 dependencies of gdmenu first off get dotnetcore 3.1 yay -S dotnet3.1-bin yay well ask you some things delete dependencies for the build once done (I usually select no) modify pkgbuild (no) start build& install (yes) next it'll complain ICU isn't installed.....thats weird isn't icu installed OOB?, fact is it's trying to find an older version (69.1) where the newest is 71.1 as of writing luckly 69.1 is still on aur so type yay -S icu69-bin like dot net same options apply after the build run the binary again and it should run
