Suggestion
Looking in system/Common.php inside helper function,
at line 621

$path = $loader->locateFile($filename, 'Helpers');

and 635

$paths = $loader->search('Helpers/' . $filename);

"Helpers" path with uppercase, but in file system folder is lowercased "helpers",
linux is case sensitive so fast fix could be replace
'Helpers' with 'helpers' and 'Helpres/' with 'helpers/' (that work for me)
or to change directory.

That's definitely an issue with the Filesystem Helper not being loaded. Can you provide the full stack trace so we can make sure the issue is locating the helper?

Aside, the folder in system should actually be uppercase: system/Helpers so if that is the root issue then this might be a problem with your installation.

Hello there.

I checked again the issue and found that problem is in my box :)
I dont find bug or issue with CI4.
Accept my apologize.

Well, the issue with my paths was because i have installed CI3 in git and later
replace files with CI4 wich caused this path mismatch.

Should I close this issue ?

No worries! Glad you found the solution and thanks for letting us know.

I'll go ahead and close it.
