This card does have a different subsystem ProductID [ 0191 ] compared to the previous model [ 0051 ]
04:00.0 Audio device [0403]: Creative Labs Sound Core3D [Sound Blaster Recon3D / Z-Series] [1102:0012] (rev 01)
Subsystem: Creative Labs Device [1102:0191]
But the ID code for the new card model has been added to kernel v5.11.7
patch_ca0132.c - sound/pci/hda/patch_ca0132.c - Linux source code (v5.11.7) - Bootlin
SND_PCI_QUIRK(0x1102, 0x0191, "Sound Blaster AE-5 Plus", QUIRK_AE5),
If you want the card supported right now you can switch to Testing branch to get kernel v5.11.10 – Switching Branches - Manjaro
But the next update on stable branch will probably have a patched kernel version in the next few days
