I launched the emulator and then tried the command npm run adb:android but it throws some error. Previously it was working on my system.

MaxPermSize=512m.This option was removed in JDK 8 and later versions, and you’re using JDK 17.0.1.Try with JDK 11, as far as I know that’s the version RN supports.
Try top put this:
org.gradle.jvmargs=-Xmx6408m -XX:MaxMetaspaceSize=6408m -XX:+HeapDumpOnOutOfMemoryErrorin your gradle.properties file. I used this as the source to the answer.
