5.1 regression from 5.0: JavaScript heap out of memory (Type instantiation is excessively deep and possibly infinit) #54542
Description
Bug Report
5.0.4 used to work fine after upgrading to the current latest version 5.1.3. Very slow builds and eventually crashes. My root-cause seems to be a circular issue of some sort with tsc.
Seems like tsc can't handle interface definition files anymore, in this case from lodash?
node_modules/@types/lodash/common/common.d.ts:194:15 - error TS2589: Type instantiation is excessively deep and possibly infinite.

~~~~~~
node_modules/@types/lodash/common/common.d.ts:206:15 - error TS2430: Interface 'ObjectChain<T>' incorrectly extends interface 'LoDashExplicitWrapper<T>'.
The types returned by 'entries().pop()' are incompatible between these types.
Type 'CollectionChain<string | T[keyof T]>' is missing the following properties from type 'ObjectChain<[string, any]>': assign, assignIn, assignInWith, assignWith, and 11 more.
206 interface ObjectChain<T> extends LoDashExplicitWrapper<T> {
~~~~~~~~~~~
My workaround was adding "skipLibCheck": true to the tsconfig.json did mitigate the issue for now.

⏯ Playground Link
The "Type is excessively deep" is being triggered in a project that includes this the @types/lodash, so in your package.json be sure you have the dependency:
"dependencies": {
"lodash": "^4.17.21"
},
"devDependencies": {
"@types/lodash": "^4.14.195"
}Be sure that you did NOT set skipLibCheck to true. So keep it to false, otherwise the d.ts files will be ignored.

💻 Code
See below, it doesn't involve my code.
🙁 Actual behavior
JavaScript heap out of memory, because of circular/ too deep dependency?
