samba - Feb 2023 - vfs_shadow_copy2 problem on top level of homes share

Hi

we have a problem accessing snapshot in a toplevel of the homes share.
Samba Version 4.16.4

In subdirectories of the homes share snapshots could be accessed.
In both cases, the snapshots are shown, but if I try to access a certain 
snapshot in toplevel of the homes share, the folder is empty in explorer
The mountpoint of the filesystem is
/data/home
Filesystem is xfs on top of lvm_thin and snapshots are generated and 
mounted by snapper
In the configured snapdir directory links are generated, which link to 
the original snapper directory

[root at serv01 ~]# ll /data/home/snapshots/
insgesamt 0
lrwxrwxrwx 1 root root 36? 8. Feb 11:05 2023-01-19--0001 -> 
/data/home/.snapshots/26304/snapshot/
lrwxrwxrwx 1 root root 36? 8. Feb 11:05 2023-01-20--0001 -> 
/data/home/.snapshots/26328/snapshot/
lrwxrwxrwx 1 root root 36? 8. Feb 11:05 2023-01-21--0001 -> 
/data/home/.snapshots/26352/snapshot/
lrwxrwxrwx 1 root root 36? 8. Feb 11:05 2023-01-22--0001 -> 
/data/home/.snapshots/26376/snapshot/
lrwxrwxrwx 1 root root 36? 8. Feb 11:05 2023-01-23--0001 -> 
/data/home/.snapshots/26400/snapshot/
...

Below the part of smb.conf


[homes]
 ??? path = /data/home/%U
 ??? read only = no
 ?? follow symlinks = yes
 ?? wide links =yes
 ?? shadow:localtime = yes
 ?? vfs objects = shadow_copy2
 ?? shadow: mountpoint = /data/home
 ?? shadow: snapdir = /data/home/snapshots
 ?? shadow: sort = desc
 ?? shadow: format = %Y-%m-%d--%H%M


accessing for example
\\SMBSERV\maurer\Downloads (?Gestern, ?7. ?Februar ?2023, ??22:02)

in explorer works fine

\\SMBSERV\maurer (?Gestern, ?7. ?Februar ?2023, ??22:02)

shows "no files" in explorer
With other shares I can access snapshots on toplevel


in the error case samba logs

The
 ? smbd_dirptr_lanman2_mode_fn: Couldn't stat
line does not occur in the working case

Could anyone confirm this problem or am I missing a config option?
I have seen, that vfs_shadow_copy2 has now more option then when I 
created the setup....
