Found solution for this problem, there is a package called apply plugin: "com.facebook.react" in app/build.gradel
so I remove it and it working again

Well, I see that you apparently solved it your way.

But I'll leave some help here for possible similar problems.

ERROR: Missing classes detected while running R8. Please add the missing classes or apply additional keep rules that are generated in /home/user/Desktop/Apps/Project/my-app/android/app/build/outputs/mapping/release/missing_rules.txt.

If you see this error in your error logs, just go to the folder where it says in the log, copy the codes that are in the missing_rules.txt file

And paste it into your proguard-rules.pro file

This worked for me, but only to build my release version.

But the builded application crashes on initialization...

The other part for my solution was to add the following line to my gradle.propeties as suggested in the R8's documentation:

android.enableR8.fullMode=false

this remove the R8's additional optimizations.
