Since updating from Angular 16 to 17, I am experiencing a TypeScript compilation issue specifically related to 'openui5'

Everything was running smoothly in Angular16. I had

"@types/openui5" : "1.40.4"
listed in my dev-dependencies. Here is how it's configured in the tsconfig.json:

{
  "compilerOptions": {
    "downlevelIteration": true,
    "sourceMap": true,
    "declaration": false,
    "moduleResolution": "node",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "target": "ES2022",
    "typeRoots": [
      "node_modules/@types"
    ],
    "lib": [
      "es2016",
      "dom"
    ],
    "outDir": "../out-tsc/app",
    "module": "ES2022",
    "baseUrl": "",
    "types": [
      "openui5"
    ],
     .
     .
  }
}

However, I encountered the following error:

Error: error TS2688: Cannot find type definition file for 'openui5'.
  The file is in the program because:
    Entry point of type library 'openui5' specified in compilerOptions

This led to many errors like doesn't exist, such as:

error TS2339: Property 'getCore' does not exist on type 'typeof ui'.

55       sap.ui.getCore().getConfiguration().setLanguage(this.getSapLanguage());
                ~~~~~~~

and no exported errors like:

error TS2694: Namespace 'sap.ui' has no exported member 'base'.

1246         static getMetadata(): sap.ui.base.Metadata;
                                          ~~~~

Upon upgrading to Angular17, which requires Typescript 5.2 or higher, these errors started appearing. In Angular16, Typescript 4.9 was being used.

Any idea what might be causing this issue?
