scMerlin scMerlin update to 2.4.0 causes global glitch on RT-AX58U @ 386.4

[pmunin]

Have Asus RT-AX3000 (asus merlin firmware for RT-AX58U v 386.4). Just updated Addons/scMerlin from 2.1.0 -> 2.4.0 and now my entire router website navigation panel is glitching out:

and devtools console is full of error:

I'm using google chrome v97.0.4692.71 on MacBook Pro (2019) (MacOs Big Sur 11.6).

Does anyone know how to fix it?
And how to downgrade scMerlin if I need to?
