I answered about how to use Custom Advanced Setup to load game with my mod in the mod comment.
For sending save, you can use https://www.wetransfer.com/ for example. Send me link to uploaded file via private messages.

Can you send me save file which crashed civ5?
I'll try to investigate cause of crash.
Also, you can try to perform turn leading to crash with my mod: https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=540914516. This mod created for similar crash issue, may be it solves your case.

Hello!

I'm skilled C++-programmer, and have some experience with Qt. But only with desktop apps, not phone. I agree with BlackXIII that it is good choice for cross platform client.

Unfortunately, I have little time to ensure my participation in development. But I would like to have access to the description of the protocol communications with the server over SignalR. Another option - to get the source code for the client running Windows, for understanding the communication protocol with the server.

The ability to gain access to the protocol or application on Windows, will give an impetus to the development of a cross platform prototype. If not me, then someone else will do it.

Yes, I can confirm that it is sufficient to uncheck only G&K and BNW in #3. This causes an unloading of corresponding DLLs and therefore clears the memory from bloat.
Ayubalugu, thanks for promoting my mod. I still often get bloated saves when my turn occurs. We need to allow more players know about it - as long as, I hope, 2K will release an update which will be contain fix for the bloating bug.
