Unable to upgrade from 9.5.10 to 10

I'm using PHP 8.1.8

I'm following the instruction from here: https://www.drupal.org/docs/upgrading-drupal/upgrading-from-drupal-8-or-later/upgrading-a-composer-based-site

bug fix after migration to drupal 10 (AssertionError: Cannot load the "entity_browser" entity with NULL ID.)

Hello,

I upgraded my project to drupal 10, I have a problem: 

When I want to filter in the media view, change the page, this does not work here is my error:
 AssertionError: Cannot load the "entity_browser" entity with NULL ID. in assert() (line 261 of /var/www/drupal/web/core/lib/Drupal/Core/Entity/EntityStorageBase.php).
here is my function load:

/**

public function load($id) {
assert(!is_null($id), sprintf('Cannot load the "%s" entity with NULL ID.', $this->entityTypeId));

Upgrade from 10.0.9 to 10.1.0 causes css/js problems

I am running a freshly installed 10.0.9 installation that I have begun building on. I have tried to upgrade the site both using composer and manually and no matter which way I've used my site breaks after the update. What happens is that the stylesheets stop loading and I get either 503 or 404 errors pointing to sites/default/files/css or sites/default/files/js. I've made sure to do the upgrade in maintenance mode, run db updates and clear caches. The only thing I can do to fix the problem is revert to my pre-upgrade backups.

Any ideas on what I'm missing here?

How to upgrade Drupal core to version 10 with modules that don't have versions compatible with both core 9.5 and 10?

I'm trying to upgrade my projects (I have 4 in total), from Drupal core 9.5.10 to 10.

It's failing with the traditional "Your requirements could not be resolved to an installable set of packages." (full message below).

I have a couple of modules installed that have versions incompatible with Drupal 10. But the next version is only compatible with Drupal 10 itself. In other words, these modules do not have a version that is compatible with both 9.5.10 and 10. These are:
