NC "folder" missing from Win 10 explorer navigation pane

I have a problem with win 10 - I had 2.5.1 RC 1 or 2.5.0 RC 1 (can’t remember exactly) installed and I wanted to update to 2.5.1final. The app showed no updates available so I went to the website and downloaded the installer. I chose to remove the old NC installation. The installation worked perfectly but now the Nextcloud navigation pane item is missing! How could I fix this?

By navigation pane item I mean the icon and text on the left hand side of explorer where you have favourites, computr, libraries, onedrive, dropbox, network and such things.

Thank you in advance!

I’m also getting this problem. Anyone found a solution?
