⚠️ Potential issue | 🟡 Minor

Use a local binder snapshot to avoid a check-then-use race.

mBinder is read twice; it can change between the null-check and call, especially since this path is triggered off the UI thread. Capture once, then use that reference.

💡 Suggested fix
 `@Override`
 public String debugBundle(boolean anonymize) throws Exception {
-    if (mBinder == null) {
+    VPNService.MyLocalBinder binder = mBinder;
+    if (binder == null) {
         throw new Exception("VPN service not connected");
     }
-    return mBinder.debugBundle(anonymize);
+    return binder.debugBundle(anonymize);
 }

In `@app/src/main/java/io/netbird/client/MainActivity.java` around lines 418 -
421, The code performs a check-then-use on the field mBinder causing a potential
race; capture a local snapshot (e.g., BinderType binder = mBinder) before the
null check and then use that local variable when calling debugBundle(anonymize)
in MainActivity to avoid mBinder changing between the null check and the call;
if the local snapshot is null, throw the same Exception("VPN service not
connected") so behavior is unchanged.
