Preview-tui Not Able to List Folder Contents

[levone1]

Linux Mint 22.2
Kitty 0.43.1
nnn 5.1

Maybe missing something obvious, but preview-tui plugin working perfectly, but shows nothing when highlight is on a directory.

Preview-tabbed, working fine, and all individual files previewing fine in preview-tui, but when moving to a folder, preview pane is blank.

If I export NNN_PAGER=ls then it will show directory contents, but obviously won't preview other files. Exporting any other NNN_PAGER results in nothing showing in preview pane.

Also tried with alias ls='eza -a' as well as many other exports and aliases, always the same.

Linux Mint 22.2 just released two days ago, so wouldn't be surprised if issue is there somewhere.

Any help with debugging? I tried removing some ...dev>nulls from preview-tui script to see if any output, but just shooting in the dark...

Thanks

Update - so just installing exa fixed it. I had assumed eza would work similarly, or that at least more or less would suffice, but only having exa installed enables showing directory contents in the preview pane

I have the same problem on Arch Linux after installing eza. Tree and ls work, but eza does not. I export this to my zshrc: export NNN_PAGER="less -P?n -R -C -~" and I do not have iconlookup enabled.
edit: nnn is compiled with: make O_GITSTATUS=1 O_RESTOREPREVIEW=1 O_NERD=1
