guava might be upgraded to 33.4.8, see details at google/guava#7811

The error message in your post doesn't show gRPC code involved.
There is indeed a usage of sun.misc.Unsafe in gRPC in netty-shaded, which is not a real issue because Netty code does check for the method availability. Refer this.

yes, it's just copyed from google/guava#7811.

we want upgrade guava and guava-jre in gradle/libs.versions.toml

# error-prone 2.31.0+ blocked on https://github.com/grpc/grpc-java/issues/10152
# It breaks Bazel (ArrayIndexOutOfBoundsException in turbine) and Dexing ("D8:
# java.lang.NullPointerException"). We can trivially upgrade the Bazel CI to
# 6.3.0+ (https://github.com/bazelbuild/bazel/issues/18743).
errorprone-annotations = "com.google.errorprone:error_prone_annotations:2.30.0"

# 33.4.0 requires com.google.errorprone:error_prone_annotations:2.36.0 but we are stuck with 2.30.0 (see above)
guava = "com.google.guava:guava:33.3.1-android"
guava-jre = "com.google.guava:guava:33.3.1-jre"

We haven't upgraded guava to 33.4+ yet because we are stuck with a lower version of errorprone-annotations for now, as mentioned in libs.versions.toml.
The static code analysis warning about deprecated sun.misc.Unsafe is only a f.y.i at this point that JDK 24+ might remove it in a future release, and is not actually breaking right now.

According to https://issuetracker.google.com/issues/342522142#comment8 (Jun 6, 2024), there is already a solution,

This was fixed in D8/R8 compilers a little more than a year ago. The issue tracking this on D8/R8 is b/281536562, but that is an internal bug.
The fix landed in 8.3.3-dev, and was part of AGP 8.3. It was backported to 8.1.44 and 8.0.46 for AGP 8.1 and 8.0.
It was not backported to D8/R8 4.0 for AGP 7.4. However, you should be able to use D8/R8 8.0.44 or 8.1.44 with AGP 7.4 if needed. To use a specific D8/R8 version merge the following into settings.gradle or settings.gradle.kts:

pluginManagement {
    buildscript {
        repositories {
            mavenCentral()
            maven {
                url = uri("https://storage.googleapis.com/r8-releases/raw")
            }
        }
        dependencies {
            classpath("com.android.tools:r8:8.1.44")
        }
    }
}
