LevelPlay Init failed after upgrading Unity from 2022.3.62f1 to 2022.3.62f2 (error 2110, Bad Request - 400)

Q&A for CVE-2025-59489

After upgrading my project from Unity 2022.3.62f1 to 2022.3.62f2 (the recent patch Unity recommended for the critical CVE fix),

my LevelPlay SDK initialization started failing with this log: LevelPlayInitError: 2110, Bad Request - 400
INTERNAL: Ke a - serverResponseString is null

Nothing else in the project was changed —

same Android App Key, same package name, same LevelPlay SDK version, same code.

Before the upgrade (2022.3.62f1), initialization worked perfectly.

After the upgrade to 2022.3.62f2, initialization always fails immediately during LevelPlay.Init().

Repro steps:
1. Use Unity 2022.3.62f1 → LevelPlay initializes normally.
2. Upgrade to 2022.3.62f2 (no other changes).
3. Build the same project for Android.
4. Launch the app → OnInitFailed is triggered with 2110, Bad Request - 400.

Additionally, in the mean time, you can use the application patcher to patch any executables you’ve made with the previous versions
