IntelliJ IDEA Run Configurations & Exception in thread "main" java.lang.ClassNotFoundException: net.fabricmc.loader.impl.launch.knot.KnotClient

[Intezium]

or java.lang.IllegalAccessError: class net.minecraft.registry.SimpleRegistry tried to access method 'void net.minecraft.registry.entry.RegistryEntry$Reference.setRegistryKey(net.minecraft.registry.RegistryKey)' (net.minecraft.registry.SimpleRegistry and net.minecraft.registry.entry.RegistryEntry$Reference are in unnamed module of loader net.fabricmc.loader.impl.launch.knot.KnotClassLoader @3c0ecd4b)

After moving the project folder, the project path changes and the IntelliJ IDEA run configurations ("Minecraft Client" and "Minecraft Server") cannot be started with the error mentioned above. If you delete the "runConfigurations" folder in the ".idea" folder, reload the Gradle project and IntelliJ IDEA, the run configuration works again.
