No need to collect the support bundle, the commands are telling us what the logs would.
The Microsoft servers are saying that the transfer should contain a certain file size, but are closing the connection before tha amount of data they said would be transferred actually was. That to me says an issue on Microsoft's side. The only recourse in my opinion is to keep trying because nobody here (including VMware) has access to Microsoft's servers to debug this.

Hey Paul-
I'm using Fusion Version 13.5.2. I didn't run any commands to download Windows 11, I simply followed the prompt in the Installation Method to "Get Windows from Microsoft". I don't know how to collect a support bundle but if you could guide me through it I can obtain that.
I tried running the command in your second response, and it appears that the job could not be finished. It is returning that "transfer closed with 309615 bytes remaining to read." Please see the screenshot of Terminal below:
If you could please confirm if this is a failed job and that this is an issue on Microsoft's side, that would be greatly appreciated.
Thanks so much for your help thus far.

Another thing to try:
Open a terminal.
Use the following command to get the URL of the downloadable ESD file from Microsoft
/Applications/VMware\ Fusion.app/Contents/Library/vmw_esd2iso getesdurl --edition edition --lang language
Example:
% /Applications/VMware\ Fusion.app/Contents/Library/vmw_esd2iso getesdurl --edition "Professional" --lang "en-us"
ESDURL : http://dl.delivery.mp.microsoft.com/filestreamingservice/files/a0a4e466-0094-4903-9d46-6421eb4b1e83/26100.2033.241004-2336.ge_release_svc_refresh_CLIENTCONSUMER_RET_A64FRE_en-us.esd
SHA1 : 6e37f71fecf4a74e5c37cd49316c874f061a2fb6
SUCCESS
The URL can be found as "ESDURL" in the output of that command.
Then, manually download the ESD from Microsoft using the following command:
curl -l esd-url > win11.esd
Example using the ESDURL from the above example:
% curl -l http://dl.delivery.mp.microsoft.com/filestreamingservice/files/a0a4e466-0094-4903-9d46-6421eb4b1e83/26100.2033.241004-2336.ge_release_svc_refresh_CLIENTCONSUMER_RET_A64FRE_en-us.esd >win11.esd
If this command fails to complete the download of the ESD file, the problem is not Fusion. It's more than likely a problem with Microsoft's download servers or some other network related issue.

This is an error that I haven't come across before. What version of Fusion are you using?
Can you try running the command again, and if it fails collect a quick support bundle, than post that in a reply to this thread?

I'm trying to download Windows 11 on VMWare Fusion on my Macbook Pro. It's the November 2023 model and it has the M3 chip.
What is causing this error? I've followed all the basic instructions for downloading Windows 11 via VMWare Fusion but I keep getting this error. I can provide additional information as needed.
