Hey @ilkin0316! Welcome to the forums!
When submitting things like this, it helps to give the entire log, because the Error: Unknown Error is typically an error with something it doesn’t recognize, BUT in the log earlier on it will likely show where the error is occurring. It usually is recognizable by a human, just not a computer.
Go get some more of that log and we might be able to find it! 
You are true. But I am a new user and I can’t upluad a .txt file((
You don’t have to, don’t worry! Just screen snipping with WinKey + Shift + S and using the snip (Not full window) will work. After each snip you can use Ctrl + V to paste the image. You should be able to upload images! You could also copy and paste the text but it will be harder to search through without the coloration of the text.

I sent output log in my ue5 project
All right! I found this problem here:
That might not be the ONLY issue, but it is definitely something that will fail a build. Your \304\ folder. You have a backslash/forward slash issue with the naming convention.
but I already deleted BP_Smoke in my project
what I have to do?(
BP_SmokeParticle has been deleted? Or BP_Smoke?
Regardless, that folder naming is the issue, not your BP_SmokeParticle. You need to rename it to something that doesn’t have forward slashes.
Also, right click your content folder in the content browser and select “Fix Up Redirectors” After ANY deletion, move, or rename to minimize reference errors.
One of my folders starts with the letter İ, it is not an English letter, could the problem be caused by this?
Oh! It is very likely. It needs to remain completely English letters. I assume that’s what \304\ is in the keyboard code!
When I rename the folder I mentioned, it is copied, another folder is created and the number of errors increases.
To test it, I opened another project and created a folder without English letters and was able to build it.
Content/\304\260lkin/Blueprints should be the only folder to worry about right now. I’m sorry, I misunderstood and thought that was the folder you were talking about and it was converting non-English symbols into \304\260 like that, creating backslashes. / and \ cannot live next to each other. Please fix this and give us confirmation of that before we continue.
Okay so I have a question. I created a new empty project and created a folder with a letter that was not in the English alphabet, and I was able to build it. If this is my problem, why I can build it?
Can you show a larger picture so we can see the names of your files?
It should be fine to click okay, as long as you right click “Content” and then select “Fix Up Redirectors”!
The Unhandled Exception I found in your build log specifically says that folder name İIkin is causing an issue. An Unhandled Exception means failed build due to this.
You have to rename that folder without the İ. Then try building again and bring back the logs if it fails again. If it fails again it will be for a different reason.
I know it is strange. Sometimes what works in one location will not work in another.
This is a blueprint from the First Person Template.
If you don’t use this, just click continue.
