This is not a Microsoft product so we couldn't comment on it.
You need to contact their support:
https://support.fortinet.com/
I know It's a third party product and I first approached them for the said issue.
But they responseded back with the details saying that it's a "Memory Corruption Vulnerability in Windows 10 SMB Server".

I had also raised the question with FortiClient Forum the only thing they shared with me is this.
Here is the link to the post:

The first link was shared by Community Member of Forticlinet. where it gives all details like "Memory Corruption Vulnerability in Windows 10 SMB Server"
