Hazem, I think you have run into the
houseboat bug.
Like the submarine bug, this seems to be no bug of CCM, but a bug in the programming of C3C. That bug was fixed in Civ 3 Vanilla, but had its comeback with C3C. The freeze of the game between turns is typically for that bug.
This bug, as the submarine bug and many other things, is fixed by the Flintlock patch, that can be found here:

You can use the Flintlock patch even during your current game. The Flintlock patch, not only in my eyes, is the greatest progress in the history of C3C and it is also in parts based on the great work of Antal1987. In the next version of CCM, the Flintlock patch will be attached to every download of CCM. If you continue your current game with the Flintlock patched exe, don´t enable the offensive artillery and the army option, as this needs additional changes in the CCM 2.50 biq.
Otherwise you have to correct your current game by finding and deleting the ship (s) with the houseboat settler (s) manually with the multiplayer tool, that is attached to the download of CCM 2.50. If the bug was triggered by the human player, you can also avoid to conquer the last city of a civilization until the ship with that settler on board is eliminated - but the houseboat bug can also be triggered by the AI conquering the last city of an AI civ, that has a settler on board of a ship.
Hazem, I had no look into your save file, as therefore I would have to accept third party cookies on my pc and since the espionage scandal with Cambridge Analytica I try to avoid all third party espionage tools on my pc. In this thread at CFC I demonstrated, how many (for a normal person uncontrolable) third party firms had a direct grip on my pc, when using CFC without being a CFC supporter at the time of that post:

As you can see in the Civ 3 succession games, you can attache Civ 3 save files directly to your CFC posts. These save files even must not be zipped, but of course they can be zipped, too.
