'Cannot find module' error on imports after Angular 9 migration Follow

Hello,

got a problem with importing components after migration from Angular 8 to Angular 9.

WebStorm underlines imports path and shows error 'Cannot find module' when path is derived from root (e.g. app/src/components/comp.component) or when aliases (@shared/comp.component) are in use. It shows everything is fine when use ../../comp.component path.

What is more, app is compiling fine.

I've already enabled angular.enableIvyMetadataSupport but it changed nothing in this case.

I suppose there's a problem with ts configuration.

My tsconfig.json (in root folder):

{
    "compileOnSave": false,
    "compilerOptions": {
        "skipLibCheck": false,
        "downlevelIteration": true,
        "module": "esnext",
        "outDir": "./dist/out-tsc",
        "baseUrl": "src",
        "sourceMap": true,
        "declaration": false,
        "moduleResolution": "node",
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "target": "es2015",
        "paths": {
            "@store/*": ["app/store/*"],
            "@shared/*": ["app/shared/*"],
            "@core/*": ["app/core/*"],
            "@assets/*": ["../assets/*"]
        },
        "typeRoots": ["node_modules/@types"],
        "lib": ["es2016", "dom"],
        "types": ["node", "jest"]
    },
    "include": ["./node_modules/@types/jest", "./src/main.ts", "./src/polyfills.ts", "./src/main.server.ts", "./src"],
    "no-import-side-effect": [true,
        {"ignore-module": "(core-js/.*|zone\\.js/.*|@angular/localize/init)$"}
    ]
}

What's wrong?
