Steps to reproduce

Run command:
vue-tsc --build --force

Attempting to utilise Typia, which fails to generate JSON transforms, presumably due to this exception.

What is expected?

Not throw exception and Typia to generate JSON transforms.

What is actually happening?

Output:

ui@0.0.0 type-check
vue-tsc --build --force

Link to minimal reproduction

No response

Any additional comments?

Possibly re-occurrence of #4783.

Have attempted to resolve, as per suggestions in previous issue, by re-installing NPM packages as follows, but with same outcome:

Uninstalled all NPM packages:

npm ci
npm cache clean --force
rm -rf node_modules

Re-installed TS Patch:
ts-patch install

Re-test TS Patch:
vue-tsc --build --force
