I can't use menu. I can't change resolution because impossible select grafics settings. And i cant start new games because button "enter" not working in "new game".
I can't configure and start game

If you go to C:\Users\ Your Username \AppData\Local\Absolver\Saved\Config\WindowsNoEditor\

you should find some ini files. In GameUserSettings.ini there are a few resolution and other settings.

I also experienced this on first load, but it has worked fine since. There is a thread on Steam Community Forum which suggests additional settings to add to the .ini files.
I guess the additional lines are read by the Unity Engine.
It seemed to work well for my system.
Remember to rename the original file to keep a Backup or Old version before making any changes. Example:
Copy Engine.ini -> rename copy to EngineBackup.ini -> Use NotePad to edit Engine.ini.
Copy GameUserSettings.ini -> rename copy to GameUserSettingsOld.ini -> Use NotePad to edit GameUserSettings.ini

The Unity Engine will read the Engine.ini and GameUserSettings.ini files when the program is launched.

It's Unreal Engine, not Unity but yeah, the ini is used by the engine, and if you add some lines like for specific options like SSAO and such, it should override the default settings.

I find only DefaultEngine. ini (D:\Games\Absolver\Engine\Programs\CrashReportClient\Config). In the C/ have not saves and GameUserSettings.ini of Absolver.
DefaultEngine have next:
[CrashReportClient]
CrashReportClientVersion=1.0
DataRouterUrl="https://datarouter.ol.epicgames.com/datarouter/api/v1/public/data"
bAllowToBeContacted=true
bSendLogFile=true
CanSendWhenUIFailedToInitialize=true
UIInitRetryCount=10
UIInitRetryInterval=2.0

There are no resolution settings.

That means the game hasn't created/generated the files yet.

Create a file named GameUserSettings.ini
and paste : Change to your resolution and see if that works.

Not working. I found C:\Users\ Your Username \AppData\Local\Absolver\Saved\Config\WindowsNoEditor\ and create GameUserSettings.ini and cgange Resolurions. But its not working.

Alright let's try adding Engine.ini too then It's really weird that something so basic isn't created. Have you tried repairing the game through GOG Galaxy ?

Try running the game as admin too.

My system put the files here as expected:

"C:\Users\ACCOUNT\AppData\Local\Absolver\Saved\Config\WindowsNoEditor"

where ACCOUNT is replaced by your specific user name.

Follow these instructions:
1. Search for and/or Run Cmd
2. type cd AppData\Local\Absolver\Saved\Config\WindowsNoEditor
3. type dir
4. type write Engine.ini
5. Press Alt, F, A . Save As EngineBackup.ini
6. Alt + Tab back to Cmd : type write GameUserSettings.ini -> Save As GameUserSettingsBackup.ini

I'm attaching versions of my EngineMod.ini and GameUserSettingsMod.ini files.
The top lines may differ from your actual system configuration: Open with Notepad or WordPad and you should be able to add lines at the bottom of the files.

When launching the program. Your application reads and/or edits the "Engine.ini" and "GameUserSettings.ini" files.
