Sigil won't launch on Windows

Hi, I'm a foreigner user so please understand my poor English skill.

I want to run Sigil on Windows 10, but it isn’t working.
I already tried installing Java,
running Windows Compatibility Troubleshooter in all available modes,
uninstalling and reinstalling Sigil,
and turning off my security programs.

But it still won’t launch!

At first, I installed version 2.6.0, then retried with 2.5.1, but neither worked.
There are no error messages—just nothing happens.

I'm using an iMac, and when I tried to install it on macOS, it worked.
But on Windows (Bootcamp), there’s no response.

Is there any solution to this issue?
This is really critical for me since it’s related to my job.
Please let me know how to fix it.
