Hi there, this is Marc. Thanks for reaching out the community.
Start by clearing the Store cache with wsreset.exe from the Run Dialog by pressing Win + R, then check that the Windows Update service is set to Automatic and running through services.msc. Next, repair or reset the Microsoft Store and Gaming Services apps from Settings > Apps > Installed Apps. It’s also worth checking the permissions on the drive you’re downloading to and making sure your account has full control. If the problem continues, run the Windows Update Troubleshooter from https://aka.ms/wudiag to repair update components. This error isn’t tied to TPM or upgrading to Windows 11, so it should be resolved within Windows 10.
Best regards,
