在使用UE5.1打包官方AR模版到手机时，程序出现闪退，并报如下错误：
“java.lang.IllegalArgumentException: com.hunanlongyue.test: Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent.
Strongly consider using FLAG_IMMUTABLE, only use FLAG_MUTABLE if some functionality depends on the PendingIntent being mutable, e.g. if it needs to be used with inline replies or bubbles.

请问在UE5.1中何解？
（目前SDK、NDK、JDK都是虚幻官方文档中推荐的版本）
