After the latest update in Manjaro-rpi4, Pikaur stopped working

[kerabromsmu]

pikaur -Vq

[Optional] Prerequisites:

Running in Manjaro on Raspberry Pi 4 (6.9.1-1-MANJARO-RPI4) update the pikaur to the latest version (pikaur-1.21-1 or pikaur-git 1.21.r9.g4862e8a-1)

Description:

When I run pikaur with or without any parameters after the update, it shows a syntax error instead of doing anything

Attached log:
