LyX ⇒ Switching Themes in LyX 2.3.6.2 MacOS Big Sur

[mv912hb]

Hello everyone!
I have installed latest version of LyX.

I am using Dark Theme on MacOS Big Sur and LyX is also in Dark Colors.
On previous MacBook also with Big Sur with the Dark Theme it was in usual regular colors everytime.
Now, when I am changing OS theme to white, LyX works in regular colors as I want, but when I am changing back to Dark which I use, LyX also goes in dark colors.

So my question is how can I set it up to always open and use regular colors, but using the dark theme on Mac?
I have not solved this using preferences, did not find anything helpful.
