ERROR - UnexpectedValueException: External URLs do not have internal route parameters.

I cannot reproduce this. The error comes from Drupal core and not the PbT module. It could help, if you could check if there is more debug information in your log.

* Do you have any link or url specific contrib modules installed?
* important: Which field types does this node have? Is there the link field type?
* Does this error come up on other node types?
* Is this node protected by PbT via term relation?

* Do you have any link or url specific contrib modules installed?

• link_attributes
• extlink

* important: Which field types does this node have? Is there the link field type?

• For simplicity's sake, I tested for this issue on a "Blog Post" content type that only has the Body field. The same error occurs. When I edit that node, it does show the "Permissions by Term" sidebox, but that is correct behavior (right?).

* Does this error come up on other node types?

• Yes

* Is this node protected by PbT via term relation?

• In the case of the Blog Post test above, no.

Here is the entire error from my logs:

Thanks for sharing this information. I am really not able to reproduce your issue. I've also installed link_attributes and the exlink modules. Then I added a linkfield to my node. I was able to edit the node, without any exception.

Maybe you can solve your issue by checking the PHP version. Please make sure, that you are using a supported PHP version. I recommend using the latest stable PHP version: 8.3. The oldest supported PHP version is 8.1.

I have seen, that you are working with XAMPP on Windows. I really recommend using DDEV: https://ddev.com/. On Windows you can use DDEV via WSL2. This works pretty well.
