[bug] Can't open Meshroom

[DakiiDakii]

Describe the bug
I just downloaded Meshroom 2025 and whenever I click on it, the command line opens up and then closes itself. I tried running as administrator, but nothing works. For a split second, it shows the following error:

Traceback (most recent call last):
File "C:\Release\sources\Meshroom\venv\lib\site-packages\cx_Freeze\initscripts_startup_.py", line 140, in run
File "C:\Release\sources\Meshroom\setuptools\initscripts\windows.py", line 34, in run
File "meshroom_main_.py", line 12, in
File "C:\Release\sources\Meshroom\meshroom\ui\app.py", line 292, in init
RuntimeError: Meshroom Command Line error: 'PROJECT' argument should be a Meshroom project file (.mg).
invalid value: '2025\Meshroom.exe'

To Reproduce
Just open meshroom

Expected behavior
Meshroom opening

Desktop (please complete the following and other pertinent information):

• OS: Windows 10
• Meshroom version: 2025

Same for me with win 11 + rtx 4090
can't see any errors because the command line opens and close very quickly

The same on Win 10 Pro
Version 2023.3.0 works

If, for some reason, you have placed the unzipped directory in the same location as I did—C:\Program Files\AliceVision\Meshroom-2025.1.0—
do not do this!
I placed the directory in any other location, for example, C:AliceVision\Meshroom-2025.1.0,
and the program started!
2023.3.0 runs under system directories too!

It seems this version doesn't handle spaces in the path.

I experienced this too. In addition, the "Publish" node is erroring because it is failing to handle a space in the project path:
