Open Project for editing

Hi
I installed pio on arch by using sudo pacman -S platformio-core then running pio home it opens browser with platform home page.
creating a project works well. but when trying to open a project for editing it opens project related directory in file manager. no matter import or new project.
imported or created project added to projects list but can’t open for editing.
previously, I tried it in vs-code using platform-io plugin on raspberry-pi but same result.
current info is Arch Linux x64, pio Core 6.1.15, Home 3.4.4

Any idea?
I searched a lot but i couldn’t find something useful.

but when trying to open a project for editing it opens project related directory in file manager

And… what program do you use there? Any screenshots?

VSCode + PlatformIO extension on Arch?

Is it the VSCodium (won’t work) or Microsoft VSCode version?

Can PlatformIO Home be opened regularly in VSCode?

no, pio home command opens in web browser, which is Firefox for me.
