CarX Street shop menu won’t let me swap engines due to GUI freeze — how can I fix it?

If the CarX Street shop menu freezes and won’t let you swap engines;

• Restart the game and your device to clear a temporary UI glitch
• Update CarX Street to the latest version from the app store
• Close background apps to free memory, then reopen the shop menu

If the problem persists;

• Try lowering graphics/UI scaling settings and re-entering the shop
• Reinstall the game (after ensuring your account is synced)
• Keep screenshots or screen recordings of the freeze
• File a complaint on Xolvie to report the bug and push for a fix
