title: Unable to build since upgrading from Angular 9.17 to 9.19
body: <p>I upgraded from Angular 9.17 to 9.19 and now ng build fails with the following error complaining about a variable declaration in both @types/node and zone.js: </p>
  
  <p>ERROR in node_modules/@types/node/ts3.5/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 &amp; typeof globalThis'.</p>
  
  <p>1 declare var global: NodeJS.Global &amp; typeof globalThis;
                ~~~~~~</p>
  
  <p>node_modules/zone.js/dist/zone.js.d.ts:600:13
      600 declare var global: NodeJS.Global;
                      ~~~~~~
      'global' was also declared here.</p>
  
  <p>It was working fine before upgrading and now won't build.  This was the only change.  </p>
  
  <p>Please help.</p>
  
  <p>My package.json</p>
