Bug running in shared environment: UnauthorizedAccessException: Access to the path "<gamedata>/ML-Agents" is denied.

[pt2302]

It looks like this is caused by the Timer.cs code, which catches IOExceptions but not UnauthorizedAccessExceptions.

ml-agents/com.unity.ml-agents/Runtime/Timer.cs

Line 480 in 2352955

catch (IOException)

This happens when the file [gamedata]/ML-Agents/Timers/[GameName]_timers.json is owned by someone else.

Hi @pt2302

Just to clarify, you'd like the code to also catch the UnauthorizedAccessException exception and log the same warning.

[pt2302]

@awjuliani, thanks for the response!

Yes, exactly. Currently, the (uncaught) exception triggers a Unity.MLAgents.Academy.Dispose() call, which then leads to UnityEngine.Application.Internal_ApplicationQuit(), interrupting the training process.
