Error says my Windows 10 NTFS C drive file system is no longer supported, hasn't synced in weeks

[KitCase]

I'm a bit desperate for a solution, I've been talking to Dropbox support and even escalated my problem to tech (who haven't been very helpful with long pauses in communication I can't get help promptly. I had to provoke another support ticket in order for them to respond again)

Everytime I startup my computer, I get an error message as such: 

This error appeared umprompted and out of the blue one day at work last week and has plagued my computer since. Dropbox has worked flawlessly on this system beforehand and now it won't sync at all.

This is all happening on the C drive of my Windows 10 computer, it is a NTFS parition and the system running the latest updates. The Dropbox folder is in the default location (in the user folder)

I have tried the following:

• Re-installed (scrubbed registry, deleted all local files, cleaned up junk files per Dropbox support instructions) 3 times
• Moved Dropbox folder (still tells me the file system is unsupported)
• Re-synced entire dropbox folder
• Re-installed with anti virus disabled

No progress. There was, though, a single day it let me run Dropbox and actually synced my folder but went right back to giving me the error near the end of the day and returned to it's old habit.

Are you using BitLocker or any other type of encryption on the drive? In the Linux world where ext4 is the supported file system for Dropbox, ext4 with encryption gives the same message (unsupported file system).

[KitCase]

I am not using any encryption. The hard drive is an NVME SSD and I have done nothing special with it really at all. Google Drive File Stream is installed on the system as well but that's all I can think of.

Are there any updates on this? I'm entering week 2 of this issue

I have been in contact with tech, nothing has changed since yesterday but now my dropbox is now working on startup and syncing this morning. I'll report back if it seems like the issue is fixed

[KitCase]

Dropbox started up this morning, it gave me the error again. Back to square one.

Sorry to hear that you’re still having trouble with this. 

I understand how important this if for you, however, as @Rich and I mentioned previously, since this requires a more in-depth investigation, I'm afraid there’s limited troubleshooting we can do here for security and privacy purposes. 

I was able to have a look again from my end and can see that a specialized member of the team is looking into this matter for you. Please direct any further info or questions you have on this to the email discussion you have with them so that they can assist accordingly. 

Thanks in advance for your patience and cooperation, @KitCase!

So quick update, my dropbox opened without error both yesterday and today. It synced my files with no issue, I was holding out on declaring it fixed yesterday until I saw it work today and I can confirm it's working on day 2
