No game finished without freezing for FAF 1.4.6.
What can i do?
Mods loaded: BlackOps FAF: ACUs, BlackOps FAF: Unleashed, BlackOps FAF: EXUnits, Total Mayhem.
It forces me to go back to vanilla.
I will try again FAF without any mods and see what's happend.

Success!

It seems that my Chrome browser have issues on that link alone, i tried with Edge and from another Chrome device and it's working.

Sorry to bother.

Hello Uveso,

This is the compressed winrar log file
game_14617376.rar.txt

Still issues...
I tried a game with mods: AI-Uveso, BlackOps FAF: ACUs, BlackOps FAF: Unleashed, BlackOps FAF: EXUnits, Extreme Wars.
After 1h:43mins the game freeze-no units are moving, game menu is responsive, pause/resume didn't fix.
I tried to Exit to Windows button and screen is black, sound is on, but nothing happend, no error, no exception messages; if i switch to windows(Alt+Tab) and reenter game no error message; no log was generated; process ForgedAlliance CPU = 09%, MEM allocated = 1,1GB.
After i kill the process i receive error

java.lang.RuntimeException: Forged Alliance Crashed with exit code 1. See game_14617376.log for more information

Re: Wyvern Battle Pack v4 for all game versions

Download link looks inactive.
Where can i download Wyvern Battle Pack v4 mod?

PS: I tried to write to main post but seems to old and i receive an error.

Thank you Uveso for your info and advice.
Surely I will try your mod.
I just installed FAF yesterday for the first time version 1.4.4 and i don't know what version was XtremWars, but in was just from FAF 1.4.4 installation.
Until now i have uninstalled default installation of FAF 1.4.4 and custom reinstalled 1.4.6 on partition where steam apps are and after 1 game everything is Ok.

PS: I played before with LOUD: BlackOps, Total Mayhem, Wyvern Battle Pack, they were great but after some time the game crashes. How many mods i can activate?

I don't think installing FAF on the same partition as the vanila game is the main issue. If that was the case then the entire game will not work.
But i will try it anyway to narrow the posibilities.

I have found another log file in C:\ProgramData\FAForever\logs\iceAdapterLogs
ice-adapter.log
and in C:\ProgramData\FAForever\logs
client.log
maybe will help.

Yesterday i have downloaded latest version FAF(1.4.4), now there is 1.4.6, hope this will be better to install.

PS: By the way how the updates are pushed to device: auto-update, need to manualy install FAF from https://www.faforever.com/, downloading the client?

I cannot install the game on C partition, but FAF is indeed installed in C (Steam apps and all games apps are on D partition).
FAF can be installed to a custom path?
I can try to remove it from C and install on the same partition D as the steam application and game folder.

No mods are run.
Now the game crashed when i click exit to windows.
In the log file i see that 'DestroyAdjacentEffects' function that throw exception because of null parameter.

Log file
game_14607080.log

PS: There is a github project where i can try find the 'DestroyAdjacentEffects' function that throw exception? I have development knowledge and maybe i can help track this issue.
The https://github.com/FAForever/fa is the project where i can search?
