I just upgraded my TYPO3 v9 to v10.04.27 and now i get an error in the Upgrade Wizard

(1/1) Error
Class 'TYPO3\CMS\Core\Cache\Frontend\StringFrontend' not found in /srv/typo3\_src-10.4.20/typo3/sysext/core/Classes/Cache/CacheManager.php line 351

As you can see in the path i also tried already with an older TYPO3 10 Version.

I disabled all extensions before the upgrade. Except the ones that cant be disabled.

So this should be a completely clean TYPO3 10 install (except the Config Files).

I dont know what i can do about this.

Here is the Full Trace:

```
Something went wrong. Please use Check for broken extensions to see if a loaded extension breaks this part of the install tool and unload it.

The box below may additionally reveal further details on what went wrong depending on your debug settings. It may help to temporarily switch to debug mode using Settings > Configuration Presets > Debug settings.

If this error happens at an early state and no full exception back trace is shown, it may also help to manually increase debugging output in typo3conf/LocalConfiguration.php:['BE']['debug'] => true, ['SYS']['devIPmask'] => '*', ['SYS']['displayErrors'] => 1,['SYS']['exceptionalErrors'] => 12290

Ajax error
Whoops, looks like something went wrong.
