[BUG] Segmentation Fault when starting a new game

[jimjamz]

Although, I have previously commented about the same error before, I did not want the steps of saving/loading a save state to conflate with that of starting a new game in case the causal effects were different.

Since my last comment, I have got the latest changes from the main branch and re-built from source.

The Force Engine v1.22.420-9-g4b48c5c3

When starting a new game, I receive the following error:

Segmentation fault

Focusing in on the point the segmentation fault occurs, I ran theforceengine binary with gdb, which reported:

2025-Sep-27 16:57:13.371 - [MemoryRegion] Allocated new memory block in region 'Landru' - new size is 1 blocks, total size is '4194304'

This section of /home/jimjamz/dev/TheForceEngine/TheForceEngine/TFE_DarkForces/GameUI/agentMenu.cpp appears to be handling events of the left-mouse click, which is what I am using when clicking 'START' to start a new game in the main menu UI, although I'm not familiar with the events, s_langKeys and k_agdel to work out what action is being performed.
Unfortunately, it doesn't appear to be possible to use keyboard keys to operate the main menu.
