Download Link Issue
I can see you're experiencing issues downloading the Godot 4.5.1 spine-godot engine module. The XML error you're seeing typically indicates a problem with the download server or the file availability.
Here are some solutions to try:
1. Try refreshing the page
Hold the Shift key and click refresh in your browser, or try accessing the download page directly at:
https://en.esotericsoftware.com/spine-godot
2. Download directly from GitHub Actions
You can download the build directly from the GitHub Actions page:
EsotericSoftware/spine-runtimesactions/workflows/spine-godot-v4-all.yml
Look for the most recent successful workflow run that includes Godot 4.5.1, and download the artifacts from there.
3. Check if it's a temporary server issue
Sometimes AWS (where the files are hosted) experiences temporary problems. Try waiting a bit and attempting the download again.
4. Try the GDExtension version instead
If the engine module download continues to have issues, you could use the spine-godot GDExtension version as an alternative while the download issue is resolved. This is also available on the same download page.
If none of these solutions work after trying again, there may be a build issue specific to the 4.5.1 version that needs to be investigated.
