Cannot reinstall wp 5.9 and plug in dir showing wrong

Hi,

I faced with the issue after update wordpress 5.9 manually from FileZilla on google cloud but it seems some permission was wrong so I tried to reinstall wp through wp page and showed error below:

Downloading update from https://downloads.wordpress.org/release/wordpress-5.9-no-content.zip…

Warning: rename(/opt/bitnami/apps/wordpress/tmp/wordpress-5.9-no-content-Y2XD5s.tmp,wordpress-5.9-no-content.zip): Permission denied in /opt/bitnami/apps/wordpress/htdocs/wp-admin/includes/file.php on line 1201
The authenticity of wordpress-5.9-no-content.zip could not be verified as no signature was found.

Unpacking the update…

Warning: copy(/opt/bitnami/apps/wordpress/htdocs/wp-admin/includes/update-core.php): failed to open stream: Permission denied in /opt/bitnami/apps/wordpress/htdocs/wp-admin/includes/class-wp-filesystem-direct.php on line 309
The update cannot be installed because we will be unable to copy some files. This is usually due to inconsistent file permissions.: wp-admin/includes/update-core.php

Installation failed.

Here is the site health check:

2 critical issues

Your site is set to display errors to site visitors
Security
Debug mode is often enabled to gather more details about an error or site failure, but may contain sensitive information which should not be available on a publicly available website.

The value, WP_DEBUG_DISPLAY, has either been enabled by WP_DEBUG or added to your configuration file. This will make errors display on the front end of your site.

Background updates are not working as expected
Security
Background updates ensure that WordPress can auto-update if a security update is released for the version you are currently using.

Warning A previous automatic background update ended with a critical failure, so updates are now disabled. You would have received an email because of this. When you've been able to update using the "Update now" button on Dashboard > Updates, we'll clear this error for future update attempts. The error code was mkdir_failed__copy_dir_retry.
Passed No version control systems were detected.
Passed Your installation of WordPress doesn't require FTP credentials to perform updates.

Can someone please take a look and let me know what might cause this issue?
