Unable to open document (Dimension 3.4.5)

[bullion85п54132342]

Hello friends and colleagues!

I can't get rid of this problem. Nobody can help. In all the topics here on the site there is no useful information.

When I work with a new document, everything is fine. As soon as I close the document, it doesn't open again. Gives an error message: "Unable to open document." It doesn't matter what's in the document, it can be completely empty, the result is always the same. The version of the program does not matter.

I have attached all the necessary files:

1) The test file

2) Problem screenshot

3) The Log file

4) Screenshot of the error itself that I see in the log file.

Can someone please help me and explain what is this error? My friends opens my files without problems.

Many thx!

Test file: https://drive.google.com/file/d/1S0kSsU-EyGkCI4CPZRadLlK2iU_G4xb4/view?usp=sharing

I repeat, it doesn't matter which file, even if it's empty. It's not about the file.

so have you tried changing the location of the files

[bullion85п54132342]

Yes, many times. Even on different drives. The result is the same

Here is the error that keeps popping up in the log file:

frontend Error 524359ms> loadError {"code":4,"debug_msg":"DCX error in dcxserialadapterdoc.cpp@218 31:AdobeDCXErrorDomain:","domain":"LoadingError","msg":"FailedDecodingDCX"}

Just in case:

1) I ran the program as administrator 

2) I have windows 10 latest. And all the minimum hardware requirements are fully compliant:

Intel Core i9-10900K, 4900 MHz

NVIDIA GeForce GTX 1080 (8 ГБ) with latest Driver

65376 МБ (DDR4 SDRAM)

Is this the end of all the help for the Adobe licensed product? And what should I do next? Get a job at Adobe and learn how to program?
