使用unity2021.3.2发布到谷歌商店了，但是在谷歌console后台中说应用频繁崩溃。崩溃的详情如下：

Exception java.lang.Error: FATAL EXCEPTION [pool-3-thread-1]

Caused by: java.lang.IllegalArgumentException: com.sundaycats.sortball: 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.

在外网或者国内找解决方案，没有一个可行性的。大部分是在Android studio里修改的。我想知道这个问题能不能在unity中修改？如果可以怎么修改？
