Camera - SCSS Error after update to 2.9

Hello,
I have two web sites using Camera template since version 2.4 or 2.5, both uses Joomla 5.4.1
The first one built from quick start package has been updated from 2.8 to 2.9 without issues.
The other one updated from 2.8 to 2.9 without errors but then when I go to "Template Options" and I enable the option to compile scss to css it fails and this error is displayed:

Can't find stylesheet to import. , 7 | @import '../sppagebuilder/addons/ut_animated_number/assets/scss/utanimatednumber'; | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ' templates/ut_camera/scss/unitemplates/utaddons.scss 7:9 @import templates/ut_camera/scss/unitemplates/unitemplates.scss 13:9 @import master.scss 9:9 @import - 1:9 root stylesheet

I went back to 2.8, installed plg_utaddons_1.2.0.zip then tried again but without success.

I don't understand why it fails saying some file are missing. Looking at the template folders on both sites it seems they are the same and /public_html/templates/ut_camera/sppagebuilder/addons/ut_animated_number/assets/scss/utanimatednumber is missing on both sites.

I need to compile scss because I have some small changes to menu.scss and preset3.css
Normally I update files in the template zip then install the edited zip but now I also tried to install your original zip without success.
Now after switching several times from 2.8 and 2.9 menu and colors are ok, but anyway I would like toi be able to compile scss
 

I just wish to add something to my previous post.
- Both web sites have the same issue with scss compilation, for some reason the site cache made the first test work
public_html/templates/ut_camera/sppagebuilder/addons for version 2.8 contains:
ut_animated_number and other ut_.. folders
while the 2.9 version contains only 
button
button_group
feature
no ut_... folder
