Deinstall Thunder Base Theme creates WSOD and reinstalling is not possible

When I deinstall the "thunder base theme" (because I use another one for the frontend) then I receive a WSOD if I view an article. The HTML looks like this then:

      <div class="field field--name-field-paragraphs field--type-entity-reference-revisions field--label-hidden field__items">
              <div class="field__item">  <div class="paragraph paragraph--type--media paragraph--view-mode--default">
          <div class="field field--name-field-media field--type-entity-reference field--label-hidden field--entity-reference-target-type-media clearfix">
    <ul class='links field__items'>
          <li><article class="media media-image view-mode-default">
      
            <div class="blazy field field--name-field-image field--type-image field--label-hidden field__item" data-blazy="">

Also re-installing of the "thunder base theme" is not working also, it shows the following error message, when to trying to enable it (via the frontend)

Unable to install thunder_base, image.style.media_image, image.style.media_image_mobile, image.style.media_image_tablet already exist in active configuration.
