This issue is because of the gradle version. You can fix it by:

• First, go to android directory and find build.gradle file
• Open build.gradle file
• Change distributionUrl=https\://services.gradle.org/distributions/gradle-6.2-all.zip to distributionUrl=https\://services.gradle.org/distributions/gradle-6.3-all.zip , using the gradle-6.3
• cmd run react-native run-android
