I'm working on a NestJs backend on multiple machines. One machine is not able to deal with the @hapi/joi package. When running the NestJs application in development mode I get this error

I tried to reproduce the problem. First, I created a new Nest application via nest new joi-test. Next I installed joi via
$ npm install --save @hapi/joi
$ npm install --save-dev @types/hapi__joi
I removed most of the code. The src directory only contains a main.ts file with
import * as Joi from "@hapi/joi";
Joi.object({
num: Joi.number()
}).validate({
port: "abc"
});
There is no Nest related code anymore so I think this has nothing to do with Nest. When removing the validation and only import the package, the code works fine.
import * as Joi from "@hapi/joi";
console.log("This is fine now");
Other machines work fine, this only appears on this machine. Any ideas how to fix it?
Update: I tested it on another company machine and this machine fails too. So my private Linux machines seem to work and my company Windows 10 machines seem to throw this error.
