[BUG] Source SDK 2013 SP - Model Browser crashes Hammer++ with default hl2ep2 game paths

[craechure]

Model Browser crashes Hammer++ when used with default HL2:EP2 game configuration, using Mapbase instead works fine with the model browser.
Probably to do with HL2 anniversary update, i think the crash did not occur before the anniversary update.

Hammer++ build 8869
