Invalid character from version change

I updated a project of mine to 4.15 from 4.14, as a copy of the original. But in the 4.15 it doesn’t want to package it, because of some invalid character in a file’s path. I have no idea, what could cause it, I even tried to rename the project’s folder from “Project_Name 4.15” to “Project_Name”.
Here is the message in the output log:

UATHelper: Packaging (Windows (64-bit)): Project.Build: ********** BUILD COMMAND STARTED **********

That last part with the ArgumentException means that it found invalid characters in the path. (It’s hungarian).
Any ideas what could cause the problem and how could I fix it by myself?

CrimsonHawk,

If you’re using a special character, please replace it with another character. If you’re not, could I please see your full error output log as a .txt file?

Thanks!

The only special character I use is that underline in the project name, but that should be OK. I will post a fresh log in about 2 hours. Is it possible to change the logging language to pure English, so it would be easier readable for you?

Provide the full error output logs when you can so I can see what else is up in your project.

Thanks!

Here it is! [The log][1]

No news about it?

The log that you’ve provided has part of the error cut out: �rv�nytelen karakterek szerepelnek az el�r�si �tban

Could you please type out the full error that’s listed with the proper words so I can translate it?

“érvénytelen karakterek szerepelnek az elérési útban” - invalid characters in the file path.

Ok, do you have any special characters in your project such as spaces, !@#$%^&*() or even letters like é or ú? If so, remove them, save the project and delete the Intermediate and Saved folder from your project and try again.

As far as I know, there is none. I used English inside the game also. The project’s path is E:\Unreal\AwEl_ZeroT\AwEl_ZeroT.uproject as it can be seen in the log file. Is there any way to know which file makes it quit? Does it have anything to do with “…/…/…/Engine/Content/Editor/Slate/Fonts/DroidSansMono.ttf” ? (Which is not mine)

What about your computer username? Is there non-traditional character being used? Also, did you delete your folders like I asked in my previous message?

Once you’ve verified that there isn’t a special character anywhere located in the file path, make sure you tried my deletion of the folders suggestion. If that doesn’t resolve the issue, please try the below suggestions.

Please try to package a newly created project, let me know if you run into the same error. If you do not, try to migrate your project from the old project into the newly created project (don’t forget to set up the project settings again) - let me know if that resolves the issue for you.

Sorry, I missed your last sentence about deleting folders. That fixed it! Thank you for your help!
