Creating new account in EOS Studio throws signatures error

Hello stackExchange community.

I am trying to follow along the Udemy Elemental Battles dApp tutorial, I have created a smart contract with login functionality and compiled it successfully, but when I tried to deploy it using eosio account I got an error:

transaction declares authority ‘{"actor":"eosio","permission":"active"}’, but does not have signatures for it under a provided delay of 0 ms, provided permissions [], provided keys ["EOS6jfCTkYUA7SYaFDKkGHjMwKEDT9JNJCNonaTGGWmN63TDPodXb"], and a delay max limit of 3888000000 ms

Looking back at the tutorial video I have realized he didn’t deploy it using eosio account,, rather he created a new account for that. Trying to create a new account I get exact same error. First I thought issue is because I have no staked RAM and CPU but neither does the guy in the tutorial and I’m kinda lost. Googling this all day and just going in circles…

Here is the actual video I’ve been watching (it’s from free course of Udemy following official elemental battles tutorial from EOS)

https://youtu.be/4uu6AbTa5Hk?t=663 => this is where I get that error.

I’m not sure what to do next. I am new to EOS backend and honestly very confused right now. I have generated couple of pub / private keys and tried creating new account using them but same error occurs. Any ideas? Thanks!!
