After running 'npm update' on my app, I am suddenly getting the following error:
Compiled with problems:
ERROR in ./node_modules/pako/lib/zlib/trees.js 257:106
Module parse failed: Unexpected token (257:106)
File was processed with these loaders:

Strange. So I compared it to the same app running on a different workstation with the same code, but where I did not run 'npm update'. The app works, no surprise.
I've seen other posts with this error, but their solutions do not seem to apply to my environment.
I cannot figure out why it's not working on my main workstation. If I copy over node_modules from the working station, the app starts fine. But as soon as I remove node_modules and package-lock.json and reinstall, the app will not start. I've removed node_modules/package-lock.json/clear npm cache. Doesn't help.
I'm comparing the module versions via 'npm ls', and they are identical on both workstations.
Both are running NodeJS 8.12.0 and npm 8.19.2
I looked at the file that it's erroring out on (pako/lib/zlib/trees.js), and it's identical on both systems.
I have no idea what 'pako' is, but using 'npm explain pako' it appears to have something to do with pdf-lib, which was never updated.
My app was built with create-react-app.
I'm at a complete loss. Here is my package.json:

I made a workaround. I compared my old and new package-lock.json of my projects and I saw some @babel lib version changed to v7.20.2 (on Nov 4th, 2022). I overwrote the new package-lock.json with old one and my react app built and ran successfully again.
I then changed (downgrade) some of @babel package in my package.json and it is solved the problem:
Put this lines into your package.json file:
"@babel/core": "7.19.6",
"@babel/generator": "7.19.6",
"@babel/compat-data": "7.19.4",
"@babel/helper-compilation-targets": "7.19.3",
"@babel/helper-create-class-features-plugin":"7.19.0",
"@babel/helper-module-transforms":"7.19.6",
