Lol, so CollisionHook, LevelHook must be disabled in v25 too... Good to know...

This crash occurs only with some maps...
With some maps a moment prior to this crash many of messages such as this one appear in the log:
Log: [CG] ActorInfo::IsValid -> PAmmo1 shouldn't be in the grid
XC_Engine: === Last line repeats 2 times.
Log: [CG] ActorInfo::IsValid -> HealthPack6 shouldn't be in the grid
XC_Engine: === Last line repeats 6 times.
Log: [CG] ActorInfo::IsValid -> Armor7 shouldn't be in the grid
XC_Engine: === Last line repeats 4 times.
Log: [CG] ActorInfo::IsValid -> Using invalid object
XC_Engine: === Last line repeats 372 times.
---
Important detail: with bCollisionHashHook=True can not reproduce FCollisionHash crash. But, stable work under crash tests sooner or later finally ends by the same error:
Critical: Assertion failed: Element.CanAcquire() [File:f:\ut_src_xc\collisiongrid\collisiongrid\gridmem.h] [Line: 139]
With XC_Engine v24 (v436-v451) and bCollisionHashHook=True that crash is easily reproduceable, same way as with standard engine.

D'oh
I had this problem on Linux and fixed it there, never recompiled the DLL with the fix on Windows.
A rebuilt DLL will be shipped for 25b

Sadly, can not test it in Linux.
Fails on Init, apparently can not load libraries because of dependency issues (OS is quite outdated...).

I had to build XC_Engine on a VDS server running ubuntu 18.04, my desktop is on 20.04 and adds even more dependencies
But, if you can use ldd to find out what symbols are missing on your system, I may try and figure out one of those ugly linker workaround (no guarantees here)

It seems, this is an issue of libstdc++.so.6 version mismatch. Found similar case discussed here:

Installed newer GCC version (v4.9.0) for experiment... (Normally this GCC version is not meant to be used with Ubuntu 14.04)
XC_Engine works now, but only with default IpDrv.TcpNetDriver.
With XC_IpDrv.XC_TcpNetDriver issues the log:
