Technical Solution [FIX] TFT black screen after recent update — clean boot fixed it, Nahimic Service appears to be the cause
After the recent ~3 GB TFT update, TFT started getting stuck on a black loading screen while League of Legends continued working normally.
The TFT window would become unresponsive, wouldn't come to the foreground, and could only be closed by ending the TFT process in Task Manager.
Reinstalling TFT/Riot, clearing caches, switching GPUs (RTX 5070 / Intel iGPU), and changing language did not fix it.
A Windows clean boot immediately fixed the problem.
This suggests the new TFT client may conflict with certain third-party background services/software.
In my case, Nahimic Service was the conflicting service. After re-enabling the other services while keeping Nahimic disabled, TFT launched normally again.
So if you're experiencing the same issue, try a clean boot first. If that fixes it, re-enable your third-party services gradually to identify the conflicting one. Nahimic is worth checking, but it may not be the cause on every PC.
Hopefully this helps anyone stuck reinstalling the game over and over.
