Hello,

I am facing the same issue. (No snap installation)

Nextcloud Version: 23.0.5 php: 7.4 nginx: 1.21.6

array(14) {
  ["GD Version"]=>
  string(5) "2.3.0"
  ["FreeType Support"]=>
  bool(true)
  ["FreeType Linkage"]=>
  string(13) "with freetype"

I found the solution. In the config.php file I had to delete all entries for the preview configuration. Thank you!
