working typescript code stopped working when I yarn install

Question

my ts code was working fine both locally and on the server but after I restarted the code on production I found there were errors(restarting installs package all over again with yarn install) and when I yarn install locally now it also creates same error

server/Startup.ts:119:12 - error TS2339: Property 'status' does not exist on type 'Response<any, Record<string, any>>'.

119           .status(HttpStatusCode.NOT_FOUND)
               ~~~~~~


Found 1640 errors.

error Command failed with exit code 1.
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.

the typescript errors are nonsense to my eyes with the experience I have now, cause I know for sure

server/routes/savings_report.routes.ts:17:17 - error TS2339: Property 'get' does not exist on type 'Router'.

17     this.router.get(
                   ~~~

the express router has the get property and the code has been working fine before

I honestly don't know where the issue is here, yarn? npm? or ts-node itself?

I tried to use npm to install the packages
I tried to clean cache of npm and yarn to install again
I tried to remove the lock files(yarn.lock and package-lock.json) to reinstall fresh from the package json.
I asked my colleague to clone and run the code (previously working code from main branch) and the same errors like these show up.

This may be caused by breaking changes in updated dependencies, which still comply with package.json versions

If you have an old yarn.lock, restore it and try yarn install --immutable, if not - try to install a specific older version of the broken dependency

I had the same problem with some protestware dependencies, fixed that by fixing to an older version with

// package.json
...
  "dependencies": { // freesed dependency version
    "event-source-polyfill": "=1.0.24",
    ...
  },
  ...
  "resolutions": { // forcefully freesed dependency in the whole tree
    "es5-ext": "0.10.53"
  }
...
