Cannot find module '/client/polyfills/index.ts' in browser console

Description:

I am trying to upgrade from 6.2.10 to 6.4.4 according to https://docs.rocket.chat/deploy/deploy-rocket.chat/additional-deployment-methods/deploy-on-debian or https://docs.rocket.chat/deploy/deploy-rocket.chat/updating-rocket.chat Everything goes well, I start service OK. But when I go to URL I see progress indicator (three dots) animating forever. When I open browser DevTools console, then I see an error:

url_common.js:80 Uncaught (in promise) Error: Cannot find module '/client/polyfills/index.ts'
    at y (url_common.js:80:1)
    at g (url_common.js:80:1)
    at d.r [as require] (url_common.js:80:1)
    at d.x [as link] (verifyErrors.js:34:1)
    at verifyErrors.js:34:1
    at dynamics_browser.js:74:1

Which is not happening with version 6.2.10.

Server Setup Information:

• Version of Rocket.Chat Server: 6.4.4
• Operating System: Debian 10.13
• Deployment Method: tar https://docs.rocket.chat/deploy/deploy-rocket.chat/additional-deployment-methods/deploy-on-debian
• Number of Running Instances: 1
• DB Replicaset Oplog:
• NodeJS Version: 14.21.3
• MongoDB Version: 4.4.13

Client Setup Information

• Desktop App or Browser Version: Up to date Chrome or Firefox
• Operating System: Windows 11

Reproduce the upgrade from 6.2.10 to 6.4.4 using the Debian tar deployment and inspect the browser stack in url_common.js, verifyErrors.js, and dynamics_browser.js. Check how /client/polyfills/index.ts is referenced during client startup; done means the browser loads the application without the missing-module error or an endless progress indicator.
