 - **Fixed backend restart loop on Windows** — Watchdog now correctly monitors the Electron process using a passed PID, preventing premature restarts during installations.
 - **Improved Java version mapping** — Version detection now correctly maps high-version servers (NeoForge/NeoMinecraft 26.x+) to **Java 25**.
 - **Fixed Startup Scripts (run.bat/run.sh)** — Implemented **Environment Injection** (JAVA_HOME & PATH) to force startup scripts to use the app's managed Java version instead of the system default.
+- **Fixed Portable Executable Stability** — Added `freeze_support()` and improved PyInstaller bundling to prevent the backend from crashing when running from the GitHub-generated `.exe`.
 - **Robust Forge version handling** — Versions like "26.1.1" now correctly trigger the Java 25 requirement.
