Your theme sacconicase seems to be the error.
However, Your currently used theme could not be found in the ww.wp.xz.cn/themes/ directory, as far as I can see.
If this was a custom theme, you may have to go back to your developer team and ask them to make the necessary change(s) to the theme.
Support of all commercial themes and plugins is out of scope for these forums. While we will not close your post, we also cannot guarantee any support at all, be that by volunteers or the developers. We recommend you instead use the developer’s official contact for their premium offerings, as that is the most direct line. As the developer is aware, commercial products are not supported in these forums.
it’s not a commercial theme, it is Underscore, a starter theme (free)

Where did you download it from?

Please contact the place you downloaded it from.
FYI, _s is now officially “archived”. The devs have said they’re no longer updating or supporting it.
OK, so what I can do with such a theme? I have invested a lot of time on my website. Has underscore became dangerous? I thought it was just a “barebone” theme, so the core of wordpress continue to run and being updated…

Consider getting another theme that’s supported and kept updated.
I recommend using a block theme, these are all free: https://ww.wp.xz.cn/themes/tags/full-site-editing/
Block themes use the new Site Editor, meaning that how you can modify a theme is now almost limitless without even having to touch CSS: https://ww.wp.xz.cn/documentation/article/site-editor/
Therefore, the theme can display as much, or as little as you want, you have full control.
There’s also a video tutorial if you prefer that style: https://learn.ww.wp.xz.cn/tutorial/intro-to-the-site-editor-and-template-editor/
Anyway it’s not the theme causing to me the error, it’s a specific function and now I opened a more specific topic: https://ww.wp.xz.cn/support/topic/function-minimum-price-to-fix-if-runnung-on-php-8-3/#new-topic-0
