Hi @piecat,
If spacedesk installer did not generate a spacedeskSetup.log, it means something is blocking our installer on your machine.
You also mentioned that you also cannot install other apps like Voicemod, Overwolf, which proves our theory.
Please try the Microsoft Troubleshooter program, it might fix the installation problem on your machine (not just with spacedesk but with other apps too).
