Install: UP201 + lots of mods.... Setting: QMB -any map-, a spitXVI or P51 stock (player) against a V1 with warhead loadout. Few seconds after mission start, it freezes and CTD. I will run a search for classfiles duplicates to see if by any chance I find the cause.

4.08m or 4.09m ? A have a 4.09m. Trying the mod on different PC's, Intels and AMDs, hardware accelerated and not, without any issues.
Hardly U will found classfile duplicates this, because this is a new one. Can U try MXY-7 instead of V-1 ? They are alike, so may be we will found something.
Still have no idea ... May be a way I use to produce engine sound... Mod based on BI-1 FM, may be the root of the issue is here...
