Selecting the most recent 1.17.1 build on GDLauncher throws an error on launch that it's the wrong minecraft version. I've manually downloading the same file directly from cruseforge and I get the same error.

Manually changing the required Minecraft version in the fabric.mod.json file to "1.17.1" got it working for me. Although, the next time I upgrade/install the mod and use it for MC 1.17.x, it will likely fail -- unless I manually fix it again.

@red2blue To manually fix:

1. Open the mods folder for your Minecraft install.
2. Find the rhino-fabric-*.jar file.
3. Open that *.jar file with a Zip file tool.
4. Find the fabric.mod.json file within the archive/jar.
5. Locate the line:

		"minecraft": "~1.16.4",

9. Change "~1.16.4" to "~1.17.1"
10. Save the change to the fabric.mod.json file.
11. Save the change to the *.jar file.

Notes:

• The location of the "mods" folder depends upon the MineCraft installation and how MineCraft is being started. Using CurseForge on OverWolf for Windows, each profile gets its own copy of the "mods" folder. (Mine is located at C:\Users\{my-login}\Documents\Curse\Minecraft\Instances\Valhelsia Fabric - 1.17\mods.)
• *.jar files are just Zip files. If you lack a good Zip file tool, you can append .zip to the file name and open directly with the Windows explorer. However, Windows does not allow editing of files within zip archives, so you'll have to extract the whole Jar file into its own folder. Then edit the fabric.mod.json file and recompress to a zip archive. After which, you'll have to ensure the correct file name and location. (It is much easier to just get the free version of 7-Zip! Which is the tool I used.)
• You have to go through this hassle, every time the mod is updated (or replaced) - until the mod authors fix the bug.
