Create a new user account to test

Create a new local account to test if the problem is caused by a user profile.

In the Settings app on your Windows device, select Accounts > Other Users.

Under “Add another user”, select “Add account”.

To create a local account, select the option “Add a user without a Microsoft account”.

Follow the instructions to complete the account setup and set it as an administrator account.

Restart your computer and log in to the account to test it

Check the taskbar loading speed. If it is normal, the original user profile may be corrupted, please follow the steps detailed in the official support article to fix it.
