This issue might be a duplicate of existing issues. Please check:

• [FEATURE]: WSL support connection and SSH forwarding #6941: [FEATURE]: WSL support connection and SSH forwarding - discusses WSL support needs for the desktop app
• feat(desktop): Add option to run OpenCode backend via WSL on Windows #5635: feat(desktop): Add option to run OpenCode backend via WSL on Windows - requests WSL backend support for the desktop app, which appears to be related to the 'Open WebUI' command not working on WSL

Feel free to ignore if none of these address your specific case.
