@testeur-990 Based on the report It's hard to determine the cause of the issue but generally with windows if this occurs then you can try removing node_modules and reinstalling your dependency

Hello @milaninfy ,
We tried what was mentioned and many other solutions we found, but we still have an issue with npm 10.8.2. I believe you can easily reproduce it by trying Node 20.18.0 with npm 10.8.2 on Windows (no issue on Mac).
For now, we have switched to Node 20.0.0, which uses npm 9.6.4, and it worked fine. We hope you can help us use npm 10.x.
Thank you

I suspect I'm seeing the same issue here -- https://github.com/TypeStrong/typedoc/actions/runs/13469139132
This job started failing randomly on Windows only after merging another branch. I tried several different versions of npm, downgrading some recently updated dependencies, but going back to 9.x doesn't seem to fix things for me... I'm tired of fighting it, and
pnpm installseems to just work, so plan on going that route for now.pranay-dutta commentedon Jun 7, 2025
