Severe crash issue

[EpicCrafter1]

I am using GZDoom version 1.8.10. When the assassins (I assume that is what they are called because they are cloaked, use 2 different weapons, and can go invisible) are introduced for the first time on Tier 2 Mission 1, the game crashes after a couple of them spawn. Please help.

I am using GZDoom version 1.8.10.

That version is old. How about trying something newer and at least check if the problem may have been fixed in the mean time?

I shall try that. I knew that is an old version, but the mod is also old, so I was thinking it might not work well on newer versions of GZDoom.
