Pirat_Nation noted in their X post that traditional fixes such as using the Windows Update Troubleshooter or clearing the update cache are often ineffective. According to them, even uninstalling in Safe Mode required multiple attempts for some users.
If none of these methods work, the most reliable solution may be to wait for Microsoft to release an official fix.
