Might be an issue with how >PHP 8 resolves paths.
It should not affect your ability to create backups.

If you run out of space on your server, UpdraftPlus will not be able to complete your backups. You will see an indicator in the UpdraftPlus logs about the space issue.

Your website supports HTTP2, and using minification can negatively affect performance. Unlike HTTP/1.1, where each request is processed one after another, HTTP/2 allows multiple requests to be loaded simultaneously. Keeping individual files unmerged and un-minified can lead to quicker loading times because each smaller file can be uploaded and downloaded in parallel, resulting in a faster rendering process for the website.

You can enable minification, but don’t merge CSS and JS files; instead, identify files that cause render blocking and defer them to improve performance.

Checking with https://tools.keycdn.com/http2-test

Your website uses HTTP2, so avoid minification to maintain performance. Instead, identify render-blocking files (JS and CSS) and load them asynchronously. You can enable minification, but don’t merge CSS and JS files; add paths to load asynchronously/defer them.

Check the browser console to see if there are any errors.
Try unchecking the option to merge js files

If you’re confident the backup was taken before the malware infection, it’s safe to restore everything. If uncertain, start with restoring only the database first, and check if everything is normal before proceeding to restore other parts if necessary

You install the premium plugin and connect your updraft account to the two sites.

Clear your cache or use another browser to see if the images are still not loading.

Hi, could you login to the cloned website and complete the restoration of the miragtion, this should activate the themes and any plugins.
In the wp admin area under Updraftplus backups
You should see a “Complete restoration” at the header section, or a “restore” button among your backup list, clicking on any of those buttons should attempt to fix the issue.
Thanks,
