Summary of the issue you are facing:
Generelly there are no previews generate on my Nextcloud Installation. I startet on version 28 so up until now I have not run a major upgrade. I tried to tweak the config.php to allow for preview generation but I am still unable to so manually and it is not done automatically either.
Memories-App is telling me, that it can access PHP-Imagick [ImageMagick 6.9.13-7 Q16 x86_64 18310 https://legacy.imagemagick.org].
On occ-level things are getting weird:
occ preview:generate /USER/files/picture.jpg
No preview generator available for file of typeimage/jpeg
occ preview:generate /USER/files/favicon.png
No preview generator available for file of typeimage/png
occ config:system:get enable_previews
false
Trying to change that via occ config:system:set enable_previews --value=“true” --type=boolean seems to work.
System config value enable_previews set to boolean true
But checking again via occ config:system:get enable_previews results in
false
Providers are all activated:
occ config:system:get enabledPreviewProviders
OC\Preview\BMP
OC\Preview\GIF
OC\Preview\JPEG
OC\Preview\Krita
OC\Preview\MarkDown
OC\Preview\MP3
OC\Preview\OpenDocument
OC\Preview\PNG
OC\Preview\TXT
OC\Preview\XBitmap
OC\Preview\Image
OC\Preview\HEIC
OC\Preview\TIFF
Baffled I am. I thought I check my config again only to find a great discrepancy between my NEXTCLOUDDIR/config/config.php

Any ideas how to fix this mess? I am happy to provide logs or files if they are missing here!
Thanks in advance,
