Missing Fiolder icons in Files page after Migration

I’ve migrated a next cloud installation 20.0.12 to another server. If I go to the files page the folder icons do not appear next to the folder names below.

I’ve run:-

sudo -u apache php occ maintenance:repair
sudo -u apache php occ db:convert-filecache-bigint
sudo -u apache php occ db:add-missing-indices
sudo -u apache php occ db:add-missing-primary-keys

but doesn’t seem to help
