If you're using Glide or some other image loading library, the cause might be this

I have already read it, and its solution seems to be to download the source code of glide-transformations and modify the source code of the RSBlur class. It seems a bit troublesome. Is there a better solution?

You can wrap the RenderscriptBlur, try-catch the blur method and recreate the blur Algorithm on exception.
But really Glide should just fix this, calling releaseAllContexts in a library is outrageous.
