So checking online most suggestions were downgrading nightly, I tried so but it didn't work.

[ganesh1997oli]

I am also facing this issue I don't know why after updating nightly this become real mess for me😌.

[CyndieKamau]

Lemme try out binary! I downloaded so many versions at this rate my toolchain's messed up 😂😂😂

[ganesh1997oli]

Finally got the solution @CyndieKamau , add this one to root folder and run cargo build --release then ./target/release/node-template --dev and it works
