I should be no stranger to builds breaking all of a sudden.

ERROR in node_modules/@types/node/ts3.4/globals.global.d.ts:1:13 - error TS2403: Subsequent variable declarations must have the same type.  Variable 'global' must be of type 'Global', but here has type 'Global & typeof globalThis'.

1 declare var global: NodeJS.Global & typeof globalThis;
              ~~~~~~

  node_modules/zone.js/dist/zone.js.d.ts:600:13
    600 declare var global: NodeJS.Global;
                    ~~~~~~
    'global' was also declared here.

It seems the bug was introduced by

https://github.com/DefinitelyTyped/DefinitelyTyped/pull/43308

https://github.com/DefinitelyTyped/DefinitelyTyped/pull/44700/commits

https://github.com/DefinitelyTyped/DefinitelyTyped/pull/41491

My (temporary) solution was to pin @types/node version to 12.12.39
