ANSWER TO – Sssweat: I run windows and the chmod ug+w -R vendor/composer command doesn't work in my enviroment, neither in cmd nor VScode terminal.

I tried icacls vendor\composer /grant BUILTIN\Users:(OI)(CI)F which is suppose do the same thing but it had no positive effect.

See if setting the composer timeout to a longer interval: composer config process-timeout 6000, then running lando composer install again works.

I had a similar situation when updating a site's drupal/core from 10.2.4 to 10.2.7 in my local dev environment. I'd keep getting the same kind of error you're talking about, where it would say that the drupal/core install failed because Filesystem.php couldn't delete some random file from /vendor/composer. I tried a couple of the other suggestions, manually removing the files and changing permissions, but to no avail.

(Not sure whether this is the same underlying problem, but here's where I got the idea to set composer timeout: https://github.com/drupal-composer/drupal-project/issues/197. See also https://www.drupal.org/project/drupal/issues/2805743)
