File tab is not showing in the Link Browser of the RTE Editor TYPO3 Backend

I have a project that i migrated from v11 to version 12.

In the Rich Text Editor when you select some text and to link it to a file uploaded of the Link Browser (To add a link to a pdf file).

Now the Tab File in the RTE to upload a file link disappeared, is there some configuration to add the "File" Tab ?

Please take a look at the screenshot to see that the tab for "File" is not there anymore after the upgrade.

I have this configuration in my setup:

I have tried to delete the configuration of bootstrap and just use the full preset = full, but still not getting the File link in the link browser.

I also tried to deleted any loaded TsConfig from the Backend.

I also uninstalled the bootstrap_package plugin and the theme plugin that running from the extension manager, no success yet.

I add bootstrap_package tsconfig for the TsConfig code here:

Here some screenshot for TsConfig code included:

Please check the Page TsConfig module and add the output to your Question:

The file tab must be removed somewhere. Either the TsConfig that removes the file tab is listed there or the preset, that is loaded.

EDIT 1:
If you have installed the EXT:lowlevel, then you can go to the "configuration" module:

There you can see, where the Presets are located:

In my answer to the following question, you can see, how to set your own custom preset:
TYPO3 RTE - allowedClasses is TSconfig have no effect

EDIT 2:
You could try to override the bootstrap theme. Add following to your EXT:your_sitepackage/ext_localconf.php:

$GLOBALS['TYPO3_CONF_VARS']['RTE']['Presets']['bootstrap'] = 'EXT:your_sitepackage/Configuration/RTE/Default.yaml';

And then add the EXT:your_sitepackage/Configuration/RTE/Default.yaml file:

imports:
    - { resource: "EXT:bootstrap_package/Configuration/RTE/Default.yaml" }

allowedTypes: 'page,url,file,folder,email,telephone'

If the file tab is not loaded then, somehow your bodytext RTE uses an other preset or there must be some TsConfig disabling the tab.
