Please provide the completed log in your IDE (e.g. Jetbrains IDLE). Without these info, we can't find out what was going wrong.

I encountered the same issue, I am developing a Fabric mod and when I try to run the "Minecraft Client" in IntelliJ IDEA, I get the following error:

Uncaught exception in thread "main"
java.lang.RuntimeException: Minecraft game provider couldn't locate the game! The game may be absent from the class path, lacks some expected files, suffers from jar corruption or is of an unsupported variety/version.

and then I check the run folder in project, the file fabricloader.log:

OK so obviously the path E:\Java-Project\Fabric ??? contains non-ASCII characters. You can do any of these tasks:

• Rename the folders to pure ASCII chracters.
• Check whether there is a mismatch on the charset of dev-injector.conf and the command line.
