Fix windows version of bun tests in CI

[konard]

We need to fix the Windows version of bun tests, or at least find out why it is impossible.

Please download all logs and data related about the issue to this repository, make sure we compile that data to ./docs/case-studies/issue-{id} folder, and use it to do deep case study analysis (also make sure to search online for additional facts and data), in which we will reconstruct timeline/sequence of events, find root causes of the problem, and propose possible solutions.
