**Your software**  
My Mautic version is: 5.2.6  
My PHP version is: 8.3.22  
My Database type and version is: MariaDB 10.11.11

**Your problem**  
I just moved a system running M5.2.6 over to composer (was non-composer install), following [How to switch to Composer — Mautic Documentation 0.1 documentation](https://docs.mautic.org/en/5.x/getting_started/switching_composer.html#), without warnings or errors during that step. The site has been running without visible problems.

I am now trying to upgrade (composer-based) to 6.0.2 following this guide: [How to update Mautic — Mautic Documentation 0.1 documentation](https://docs.mautic.org/en/5.x/getting_started/how_to_update_mautic.html#updating-mautic-composer-based-installs). I changed all occurrences of 5.2.6 to 6.0.2 in `composer.json` and ran `composer update --with-dependencies`.  
This produces a lot of errors, and the php commands (`cache:clear` etc) don’t work anymore.

First, there are some warnings in this build step:

```auto
> npm ci --prefer-offline --no-audit
npm WARN deprecated osenv@0.1.5: This package is no longer supported.
npm WARN deprecated inflight@1.0.6: This module is not supported, and leaks memory. Do not use it. Check out lru-cache if you want a good and tested way to coalesce async requests by a key value, which is much more comprehensive and powerful.
npm WARN deprecated @npmcli/move-file@1.1.2: This functionality has been moved to @npmcli/fs
npm WARN deprecated rimraf@2.7.1: Rimraf versions prior to v4 are no longer supported

npm WARN deprecated debug@3.2.6: Debug versions >=3.2.0 <3.2.7 || >=4 <4.3.1 have a low-severity ReDos regression when used in a Node.js environment. It is recommended you upgrade to 3.2.7 o

```

Then, after updating themes and co. these errors. (Project root is `/var/www/begegnung`):

Another observation (perhaps related??): Restoring the codebase (via restoring `composer.lock` and `composer.json`) and `composer install` does not work for me, but resets the site to the “Mautic is ready to install”. If it’s not related, I do not care about this.

Any help on these errors is greatly appreciated!
