Files in subdirectories not syncing

I'm experiencing issues with files in subdirectories failing to sync. I can create a directory, and this correctly appears on the drive (I can see it appearing on my Windows VM). However, any file I create within it won't sync:

If I stop and start onedrive-client it does successfully sync test.txt.

If I then create a subdirectory of this one, it still won't sync:

However in this case it won't create it even after restart:

I am experiencing this for other nested directory structures too, although I have one that has partially replicated (but not to its full depth) - I can't see how it differs from my tests.

Any suggestions?

That's weird and looks like a problem on the Microsoft side Microsoft.SharePoint.Client.ResourceNotFoundException.

Can you give me well-defined steps to reproduce it, then I can work on.
(As far as I understood, if I create a dir and then a file inside this dir, it won't work?)

Sorry for the delay, I've been away. I've found it to be a bit weird and inconsistent - as I said, some things sync and some do not. However, here's some stuff I just did:
mkdir test
This syncs OK.
mkdir test/test1
This fails:

touch test/test.txt
Nothing happens, no log output.
Restart onedrive-dclient. The file test/test.txt then syncs OK but the dir test/test1 does not:

Restart onedrive-client The file test/test2.txt syncs but still no sign of the dir test/test1, errors as before.
