Gas Estimation Failed

Hello everyone.

I am getting the "Gas estimation failed" error while trying to solve the last 3 levels of Ethernaut (Stake, Impersonator, Magic Animal Carousel). How can I solve this problem? I am facing this problem while trying every solution on the internet.

I'm trying to use the following two resources for "Stake" challenge.

Thanks in advance
