Preparing metadata (pyproject.toml) did not run successfully [BUG]

[Synthesized]

Describe the bug I am unable to completely start the editor and get the "Could not connect with backend" error.. I'm getting the 'ModuleNotFoundError: No module named 'websockets'' line, but the preceding lines are different from those listed on the troubleshooting guide. I have removed and reinstalled NodeJS, Python, and git, but had no change. Have confirmed pip is installed, running 24.2.

To Reproduce Steps to reproduce the behavior:

1. Open run.bat

Expected behavior Editor to run normally.

Save file and log.txt Console error lines:

**Additional context**
It mentions requiring Visual C++ 14.0 or greater installed, but I have 14.40.33816 installed.  I am running Windows 11 Home.  I apologize if I've missed something very basic.  Appreciate any assistance you can provide.  Thank you!

Same issue. Windows 10 Pro laptop that is not my gaming rig but thought I'd install and look at my saved game files. Error log similar to OPs is attached. I also have Visual C++ updated.

The 'where python' at the command prompt returns the .exe's correct path. Version = 3.13.0

I have that exact same issue. This has worked before with this exact location as well but before I reset my laptop a few months ago. Now it never works.

Here is what it says for me:

I'm sorry buit this is an issue that I have had on my personal laptop with python and at work and have no idea how to get around with it. To be more precise, the: × Encountered error while generating package metadata. ╰─> See above for output.

note: This is an issue with the package mentioned above, not pip.

So I'm sorry if for now I can't help you :(

[Synthesized]

Appreciate you responding Urreta. Just happy to know I didn't do something dumb.

Since you mentioned you have seen the error as well I searched for it in google and found some comments that mentioned downgrading Python solved the issue. Figured it was worth a shot, installed 3.10.11 (and I needed to delete and redownload the editor as well since it was looking for the newer python directory), but the editor opened correctly, connected successfully, and seems to be working as intended. Haven't tested all of the functionality, but seems to be fine. I didn't test any higher Python versions to see exactly when the break occurs, but for right now 3.10.11 works.

[geoffp89]

Will try rolling back and report in, thanks.

Will try rolling back and report in, thanks.

Solved 3.10.11 installed. Deleted editor folder and re-installed. Seems to be working fine.

[IUrreta]

Great!

[IUrreta]

Just out of curiosity, what version of python were you using before?

[Synthesized]

Latest available on the website, 3.13.0.

[geoffp89]

3.13.0 as well as 3.11
