后端不响应 HTTP 请求

Question

I know that the information that follows is most certainly not enough to solve my problem and I may specify what is needed when and if needed.

The situation is the following. I was programming normally and, as I did, I made a PUT request to my application backend. The browser tab suddenly logged many (like, many) errors concerning different information which I cannot remember due to the fact that it closed itself soon after. Almost at the same time, both VSCode windows I had open and running the backend and frontend of the application closed themselves.

Since then, the backend does not appear to answer any HTTP request made to it. It doesn't get to the point in which the code of the controllers run, for I have put a console.log there and nothing is logged. Similarly, no errors are shown in the console when the request is made. It still connects to an MQTT broker, as it was supposed to.

The Insomnia request loads forever unless I cancel it, and, Insomnia still notices when the connection is reset, giving the

Failure when receiving data from the peer

error.

Lastly, the frontend created a debug.log file in the project's folder that contain 21 lines that read

[0624/203732.834:ERROR:crash_report_database_win.cc(428)] unexpected header

with the only difference being the numbers in the start, and, also created a yarn-error.log, a very long log with a line that caught my eye (because it had the word "Error" in it) that reads, among other things,

Trace: Error: EBUSY: resource busy or locked...

I have no clue what happened or what I should do.
