Hi! This could be due to an interrupted build. Could you try again after deleting this folder? C:\Users\[USER]\AppData\Local\Temp\[COMPANY]\[PROJECT]\LLMUnityBuild The company name will be "DefaultCompany" if you haven't specified it in Unity

The above solution should resolve the issue, let me know if you still face it

Same happen to me on unity 6000.0.24f1. Need to restart my computer to build (and not clic on play button before). I got the error even if i restart unity, directly whene scene open in editor.

can you also delete the Assets/StreamingAssets/undream* folder, restart Unity and wait for it to be downloaded again?

[ate864]

ok i deleted temp folder and streamingAssets content folder, restart unity , it start downloading zip file in temp folder, extract it in streamingassets folder, remove the zip file from temp folder, "Download Complete" i click play mode (android demo scene) > all is ok no error. Build on android > UnauthorizedAccessException: Access to the path 'undreamai_windows-avx2.dll' is denied. the temp folder get all the platforms but the streaminasset folder can't be totaly empty, it stay some platforms with windows-avx2. The LLMBuilder.cs script can't remove the undreamai_windows-avx2.dll , need to stop it before .

looklike https://github.com/undreamai/LLMUnity/issues/250

also, in the temp folder stay the windows-avx2 folder, so error "file exist" appear.
