Save Color Scheme throws error (WSOD)

Why won't this be fixed?
drupal_get_path() is removed and can't be called upon in D10.It is still present in the color_submit.php file which is part of AdaptiveTheme.
So as far as I understand it should at least be corrected here before we can carry on.

please review the patch.

Thank you for the patch. But the patch will not work, Because it removed the trailing slash as well, Also there is one more occurrence.
So I have created the MR to fix issues from all places.
Please review,
Thank you.

Updated issue summary with the actual error.

After correcting the color_submit.php file according MR4! following error is thrown when I want to change te colors:

ArgumentCountError: Too few arguments to function Drupal\Core\Asset\CssOptimizer::__construct(), 0 passed in /data/sites/web/modelspoorhobbybe/subsites/empa2019.modelspoorhobby.be/themes/contrib/adaptivetheme/at_core/forms/color/color_submit.php on line 132 and exactly 1 expected in Drupal\Core\Asset\CssOptimizer->__construct() (line 34 of core/lib/Drupal/Core/Asset/CssOptimizer.php).

The code in the patch is good, as the previous error message has disappeared from the log.
Once applied, only the CssOptimizer error remains.
I think the patch covers the original bug.

Neither the patch nor the merge request work. The patch from roshni27 fails to copy the theme logo because the trailing slash is missing so that it fails to find the logo.

The merge request leads to the following error:

Uncaught PHP Exception ArgumentCountError: "Too few arguments to function Drupal\Core\Asset\CssOptimizer::__construct(), 0 passed in web/themes/contrib/adaptivetheme/at_core/forms/color/color_submit.php on line 132 and exactly 1 expected" at web/core/lib/Drupal/Core/Asset/CssOptimizer.php line 34" while reading response header from upstream

This has been fixed and will make its way into a new release later today
