when starting the laptop an error appears indicating the BitLocker keys could not be read from TPM. Need to manually enter the recovery key. Upon entering the recovery key and booting into Windows, device manager shows the TPM is in a faulty state

The issue you're experiencing with BitLocker not being able to read the keys from the TPM (Trusted Platform Module) and the TPM being in a faulty state can be caused by several factors. Here are some steps you can take to troubleshoot and potentially resolve the issue:

1. Check for Updates: Ensure that your system has the latest updates installed, including the latest Servicing Stack Update (SSU) and any cumulative updates for Windows. Additionally, check for updates to the BIOS Firmware or TPM Device Firmware from your manufacturer's support website.
2. Clear and Reinitialize the TPM: If the TPM is in a faulty state, you may need to clear and reinitialize it. Be aware that clearing the TPM can cause data loss, so ensure you have backups of your data. You can follow the instructions in the article on how to clear all the keys from the TPM.
3. Device Manager Check: Open Device Manager and check the status of the TPM. If it shows as faulty, you might need to uninstall the Trusted Platform Module driver and perform a hardware scan to allow Windows to reinstall the correct driver.
4. Contact Support: If the issue persists after trying the above steps, consider contacting your hardware vendor or device manufacturer for further assistance in diagnosing the TPM device.

By following these steps, you should be able to address the issue with the BitLocker keys and the TPM state.
