how to convert a html-report into a csv-report

Well, try this to see if there are any objects in $Report that would pass the Where-Object filter:

$limit = 5000000000

$props = @(
    @{ Label = 'SizeType'; Expression = { $_.Size.GetType().FullName } }
    'Size'
    @{ Label = 'SizeExceedsLimit'; Expression = { $_.Size -gt $limit } }
)

$Report | Select-Object -Property $props

Hello
The Script above give me a result like this (picture is in the attachment).

There you go, then. The sizes were all under your specified limit, so the reports are supposed to be empty.

mhh now i get it
You’re genius thanks
But again a question now does $Report contain only the Sizes and if there are true or false, but is it possible to add the owner and the folder names ?

The last code I posted was just for debugging purposes, you can remove it from the script any time. It did not actually change the value of $Report, though; just used $Report as a starting point.
