Failing tests

[mmagician]

When I try to run yarn test, I get two errors, seemingly randomly one then the other:
1:
Error: Valid private key was not found in 8 iterations. PRNG is broken
2:

ChatGpt helps a lot. I faced the same problem. Then I asked ChatGPT with the error information, and I was asked to install some libraries with "npm install xxx", such as "ffjavascript", and update the dependencies with "npm install circom_tester@latest snarkjs@latest ffjavascript@latest". Finally, it starts to work.
