Oy there's a lot going on there... so here's what sticks out to me:
Remako_HD_Graphics_Mod_BETA_0.1 - This is both outdated and in the wrong place with respect to load order. If you're dead set on Remako, get the current builds from CaptRobau's blog. The new files are also split up and named in a way that makes their proper load slot clearer. Alternatively, add Strife's
"Mods of the Round" catalog to get easy loading of newer (and IMHO better) options.
Animations - Can break things, especially when combined with New Threat or Reunion (which DLPB just released a massive update for earlier today, but is incompatible with the 7H ecosystem)
Gameplay - I personally don't use anything here, but since it affects things at the EXE level, can never be ruled out as being part of the reason for crashes.
Reunion - The extant catalog has a VERY old version of this (R03). If you want to keep it, you must change the exe file in 7H's "General Settings' window to ff7_bc.exe. Otherwise instability and graphics glitches will rule the day. As noted, since this requires an alternative exe file, pairing it with the 'Animations' and 'Gameplay' mods can result in instability and crashes.
