PHPStorm 2020.3.3 - Windows 10, WSL2 Ubuntu distro location not visible
I've installed WSL2 and Ubuntu distro, everything works fine from a Windows perspective but I can't open my code in PHPStorm - location is not visible.

I see my partitions, but WSL is not visible. It is visible in in Windows Explorer though:

I was doing the same thing on my second PC and everything works fine there.
I've tried opening it just typing the path - it isn't working either.
Only difference between this PC and the other is: on the first (working) one, I've installed Ubuntu using Windows Store app, so it installs on C partition in %appdata%. On this one I've installed it manually on a different partition.
Could that be a source of my problem?

It might be this one: https://youtrack.jetbrains.com/issue/IDEA-252213
Could you please check how it goes for you on 2021.1 RC? https://www.jetbrains.com/phpstorm/nextversion/
Well, I guess you're right Eugene Morozov. Updating to 2021.1 RC helped, I can see my distro now. Thanks!
Please check "wsl" related settings in the built-in IDE registry (Help > Find action > Registry), do you have the same set of enabled settings?
Also, have you checked the log file already (Help > Show log in Explorer)? Do you have any WSL-related errors there?
After checking the log file you suggested, I found these errors:
2022-04-14 07:07:54,120 [63706217] INFO - ion.wsl.WslDistributionManager - Cannot load WSL distributions with versions: wsl.exe is not found in %PATH%
2022-04-14 07:09:22,337 [63794434] INFO - j.ide.actions.RevealFileAction - Exit code 1
Something def chaned - before the path was \\wsl$\Ubuntu\ , now its \\wsl.localhost\Ubuntu
UPDATE: turned out just putting C:\Windows\System32\ as value for PATH variable fixes the problem, I probably broke PATH variable at some point, since I could not restore the original value, I just put this general path.
It was not a phpStorm issue. Thank you for your help.
Thank you for the update and for sharing the solution!
