Local Deployment Fails on Windows Due to Malformed Path

Hi Convex team, I'm having trouble running a local deployment on Windows. When I run: 
bun dev:backend --once
bun dev:backend --once
I get the following error: 
✖ Error: Unable to start push to http://127.0.0.1:3210
✖ Error fetching POST  http://127.0.0.1:3210/api/deploy2/start_push 400 Bad Request: InvalidExternalModules: Hit an error while pushing:
Loading the pushed modules encountered the following error:
ENOENT: no such file or directory, mkdir 'C:\C:\Users\admin\.convex\anonymous-convex-backend-state\anonymous-nh4\convex_local_storage\modules'
✖ Error: Unable to start push to http://127.0.0.1:3210
✖ Error fetching POST  http://127.0.0.1:3210/api/deploy2/start_push 400 Bad Request: InvalidExternalModules: Hit an error while pushing:
Loading the pushed modules encountered the following error:
ENOENT: no such file or directory, mkdir 'C:\C:\Users\admin\.convex\anonymous-convex-backend-state\anonymous-nh4\convex_local_storage\modules'
As you can see, the path is malformed (C:\C:\...). Here’s what I’ve tried so far: - Running as administrator. - Deleting the .convex directory in my user folder to reset local state. - Ensuring there are no malformed paths or double drive letters in my .env.local. - Checking for any custom CONVEX_TMPDIR or related environment variables. - Attempting to set CONVEX_TMPDIR to a directory on the same drive as my project, using PowerShell: 
  $env:CONVEX_TMPDIR="C:\Users\admin\convex_tmp"
  bun dev:backend --once
 
  $env:CONVEX_TMPDIR="C:\Users\admin\convex_tmp"
  bun dev:backend --once
Despite these steps, the error persists and the deployment crashes. I’ve also reviewed the Discord discussions about similar issues, and it seems there may be a bug in the Convex CLI’s handling of paths or the CONVEX_TMPDIR variable on Windows. Is there anything else I can try, or is this a known issue with the CLI on Windows? Any help would be appreciated!
