My answer is based on the assumption that your version is Windows Home.
I have highlighted below some important parts of the message:
Reasons for failed automatic device encryption: Hardware Security Test Interface failed and the device is not Modern Standby, TPM is not usable.
This message arrives when device encryption is unavailable in Control Panel.
It is only shown in
msinfo32.exe as the reason for this missing option.
The situation is that the TPM is usable and would work with Bitlocker,
but not with device encryption.
The important part here is the word "automatic".
Microsoft is saying that it would have enabled device encryption automatically
if all the requirements were fulfilled and the login was with a Microsoft account.
In this case, the all-important recovery key would be saved to your
OneDrive cloud storage for future recovery.
A Windows Pro user would not be required to back up his key to the cloud,
nor to have a device with certain capabilities, as Bitlocker will work
He could even choose to use a password instead of the TPM (which Microsoft
frowns upon as an unsafe practice).
Microsoft is here protecting Windows Home users, supposedly acting in their
best interest by not enabling disk encryption automatically.
Home users are assumed to not know enough about disk encryption,
so this keeps them from unknowingly using encryption and possibly locking
themselves out of their computer in the future,
even rendering their data inaccessible.
In short, this is a warning that you can ignore if you don't intend to encrypt
