Typo3 10.4.4 Gridelements 10.0.0 extension not working – SEO

Hey I am pretty new to typo3 and I want to build a website.
I am running version 10.4.4 of TYPO3 with the bootstrap package installed.
I have tried to follow the guide on https://docs.typo3.org/typo3cms/extensions/gridelements/stable/

I have copied the TypoScript into my template setup, but there is no output on the frontend.
Remember I am new to this so I don’t understand the TypoScript well yet.
So any ideas to what I could do?

EDIT:
I want to use GriElements so that I can create my own layouts on my page. The standard layouts are good but I need more freedom than what they offer.

I can get output on the frontend without GridElements, but when I use the extension only the content in the GridElements block wont show. If I remove the standard TypoScript from the example on the manual page for this extension i get an error saying "Oops an error occurred! Code:" and then a code that changes every time I update the page.

My TypoScript on my template looks like this:

page.includeCSS.1 = fileadmin/user_upload/template/css/fonts.css
page.includeCSS.theme = fileadmin/user_upload/template/css/custom-theme.scss


# plugin.tx_bootstrappackage._LOCAL_LANG.da.readmore = test (NOT WORKING)
# https://docs.typo3.org/m/typo3/reference-coreapi/10.4/en-us/ApiOverview/Internationalization/ManagingTranslations.html

page.meta.robots = noindex, nofollow
page.meta.robots.replace = 1
page.10.partialRootPaths.3 = fileadmin/user_upload/template/partials/ContentElements/
page.10.partialRootPaths.4 = fileadmin/user_upload/template/Partials/Page/
page.10.dataProcessing.10.levels = 3
page.includeJSFooterlibs.bootstrap_navbar = fileadmin/user_upload/template/js
page.includeJSFooterlibs.bootstrap_navbar = fileadmin/user_upload/template/js/navbar.js
lib.contentElement.partialRootPaths.20 = fileadmin/user_upload/template/partials/ContentElements/
lib.contentElement.partialRootPaths.20 = fileadmin/user_upload/template/Partials/ContentElements/



lib.gridelements.defaultGridSetup {
  // stdWrap functions being applied to each element

  columns {
    default {
      renderObj = COA
      renderObj {
        # You can use registers to i.e. provide different image settings for each column
        # 10 = LOAD_REGISTER
        20 =< tt_content

        # And you can reset the register later on
        # 30 = RESTORE_REGISTER
      }
    }
  }

  # if you want to provide your own templating, just insert a cObject here
  # this will prevent the collected content from being rendered directly
  # i.e. cObject = TEMPLATE or cObject = FLUIDTEMPLATE will be available from the core
  # the content will be available via fieldnames like
  # tx_gridelements_view_columns (an array containing each column)
  # or tx_gridelements_view_children (an array containing each child)
  # tx_gridelements_view_column_123 (123 is the number of the column)
  # or tx_gridelements_view_child_123 (123 is the UID of the child)

}

lib.tt_content.shortcut.pages = COA
lib.tt_content.shortcut.pages {
  10 = USER
  10 {
    userFunc = tx_gridelements_view->user_getTreeList
  }
  20 = CONTENT
  20 {
    table = tt_content
    select {
      pidInList.data = register:pidInList
      where = colPos >= 0
      orderBy = colPos,sorting
      orderBy.dataWrap = FIND_IN_SET(pid,'{register:pidInList}'),|
    }
  }
}

tt_content.shortcut.5 = LOAD_REGISTER
tt_content.shortcut.5 {
  tt_content_shortcut_recursive.field = recursive
}

tt_content.shortcut.20 {
  0 {
    tables := addToList(pages)
    conf.pages < lib.tt_content.shortcut.pages
  }
  1 {
    tables := addToList(pages)
    conf.pages < lib.tt_content.shortcut.pages
  }
}

tt_content.gridelements_pi1 >
tt_content.gridelements_pi1 = COA
tt_content.gridelements_pi1 {
  #10 =< lib.stdheader
  20 = COA
  20 {
    10 = USER
    10 {
      userFunc = tx_gridelements_view->main
      setup {
        default < lib.gridelements.defaultGridSetup
      }
    }
  }
}

The error I get:

Tried resolving a template file for controller action "Standard->3" in format ".html", but none of the paths contained the expected template file (Standard/3.html). The following paths were checked: /httpdocs/typo3conf/ext/bootstrap_package/Resources/Private/Templates/ContentElements/, /httpdocs/typo3conf/ext/gridelements/Resources/Private/Templates/
