Taskbar issues fixed via Known Issue Rollback
Microsoft has already addressed the taskbar errors caused by the Windows 11 May 2024 Preview Update by using Known Issue Rollback (KIR) to roll back faulty non- security delivered through Windows Update.

While the fix may take up to 24 hours to automatically push to consumer and unmanaged business devices, customers can speed up the deployment by restarting Windows .
To resolve this known issue with Windows 11 updates on affected Windows managed devices, administrators must install and configure a KIR Group Policy. After installation, the Group Policy can be found under Computer Configuration -> Administrative Templates -> Windows 11 22H2 KB5037853 240505_142035 Known Issue Rollback.
To deploy the Known Issue Rollback, you will need to access the domain policy or local computer policy on your domain controller through the Group Policy Editor. From there, you can select the specific version of Windows you want to target.
Detailed instructions on deploying and configuring KIR group policies can be found on the Microsoft support website
