Bug reports without an attached log file are usually useless.
Works rather fine with CarotDAV, but the developer version 5.10 stops with error "Could not sent request body: an existing connection was closed by remote host" (translated from German) after 47 – 130 MB (tried it several times).
So I think it is a WinSCP limitation / bug.
One remark: files more then 100 MB are breaks off (not uploaded until the end). But, it is not a fault of WinSCP. Apparently, it's a limitation of the OneDrive webdav access itself.
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters
will increase the limit to 4 GB.
