Insurgency inconsistent successful launch rate

**Game information**
Insurgency

**Distribution name and version where applicable**
NixOS 25.05

**Flatpak info**
Flatpak 1.16.0
nvidia-570-86-16
default
host

**Problem description**
Very inconsistent success rate of launching the game, majority of the time game doesn't launch at all, very rarely it does.
Not related to library issue that plagued in the past due to the block-list existing for this game.

**Does this issue reproduce with native Steam**
**No**

Start by reproducing the launch failure with the Flatpak Steam setup and inspect insurgency.sh at line 65 alongside the shared-library-guard and malloc() abort messages in the report. Done means Insurgency launches consistently through Flatpak without the reported abort.
