wordpress update theme error

[puhapuru]

Hi, I have tried to update helium theme 5.4 from 5.3 and I got this error.

Twig\Error\RuntimeError thrown with message "An exception has been thrown during the rendering of a template ("ERROR: CSS Compilation on file 'helium.scss' failed on error: Incompatible units rem and %.: wp-content/themes/g5_helium/scss/helium/sections/_offcanvas.scss on line 35, at column 3 Call Stack: #0 import wp-content/themes/g5_helium/scss/helium/sections/_offcanvas.scss wp-content/themes/g5_helium/scss/helium.scss on line 92 #1 import wp-content/themes/g5_helium/scss/helium.scss (unknown file) on line 2")."
