Win10 Built-in Feedback Hub fails to load and shows a blank page after the latest update

Because Feedback Hub works normally in another account on the same PC, the evidence points to data or configuration scoped to the affected user profile rather than a device-wide installation failure. First sign in to the affected account, open Settings, Apps, find Feedback Hub, open Advanced options, and run Repair. If that does not help, use Reset after noting that reset can remove that app’s local data. Restart and test the app before reinstalling again. Next, compare whether the affected account has a work or school connection, proxy, or security product that the working account does not. Avoid deleting profile folders or registry keys to clear the page; that can damage unrelated settings. If reset still leaves the page blank, use the working account to submit a Feedback Hub report with the Windows version, update history, and a screenshot, and test a newly created local account before migrating the profile.
