Apache can't open files in Dropbox anymore

Hi,
I am using an Apache 2.4.41 server which DOCSROOT directory is in a Dropbox drive. It's been always working fine until 2025-05-01, when my Dropbox client asked me for an update. I consent and immediatelly the Apache server stopped working. It seems it cannot open the files the way it did. If I move the web files out of the Dropbox drive (and I configure Apache to use the new location, of course) it works again. The error I'm getting is this one:

Warning: Unknown: failed to open stream: No such file or directory in Unknown on line 0
Fatal error: Unknown: Failed opening required 'E:/Dropbox/Web/index.html' (include_path='.;C:\php\pear') in Unknown on line 0

Any way to fix it or workaround it?
Thanks.

    Hi.
    If it serves I'll tell you my "solution". I was also using an older version of PHP. It couldn't open any Dropbox files after updating to the latest version. Updating PHP didn't work, so I downgraded the Dropbox client and everything went back to "normal".
    A month ago, I switched (permanently) to Linux, abandoning Windows. Now everything works by default.

    After a Dropbox update, Apache stopped opening files from Dropbox, showing a "failed opening required" error. Moving files out of Dropbox fixes Dropbox is stuck syncing forever, waiting to sync, not starting, or monkey type  files are not uploading. If your Dropbox desktop app is stuck syncing, waiting to sync, or not starting to sync, Try logging into your account on dropbox.com to see if they are there. You or someone who shared or unshared the files or folders may have accidentally moved, renamed, or deleted them.
