debug cr

Cause:

Java crypto system failed during static initialization because it couldn't retrieve a serialized encryption key file.

Fix/Debug Steps:

1. Check key file exists & permissions

   ls -la keyfile.ser
   chmod 644 keyfile.ser

1. Verify Java 8 environment & classpath

   java -version

1. Regenerate corrupted key - Delete keyfile.ser and let app recreate it

2. Check serialization compatibility - Ensure key was created with same Java version

Quick fix: Locate missing keyfile.ser, ensure readable permissions, or delete to regenerate.
