I solved the problem by reinstalling minecraft and rebooting

When I write grandlew genIntellijRuns in cmd, I get an error after a few seconds: > Task :downloadAssets FAILED FAILURE: Build failed with an exception. * What went wrong: Execution failed for task ':downloadAssets'. > Failed to get asset: minecraft/lang/ru_ru.json Some assets failed to download or validate, try running the task again. How I can fix it?
