Ah man, I’ve been trying to replicate this issue.

Just a quick rundown questions to evaluate -

  1. Which browser are you using? Does your browser have metamask extension installed?
  2. I’m assuming you did not make any changes to the code other than your .env file. Correct me if I’m wrong.
  3. Your server is up and running ? I’m assuming yes.
  4. Did you install all the dependencies again? By running yarn install?
#25 
my browser is Microsoft Edge and i have metamask install
my server is runner and i have all the dependencies installed by using yarn install

i did not change anything rather than inserting my server and app ID in the .env file
#26 
thank you sir, i just  switch my browser to chrome 
and it worked, even yarn web work without any provider error
