It looks like it is trying to build an image - if you remove the imagename parameter, does it then start the container? i.e. try with the simplest container generation. That works here - and also try to clean up your docker file system maybe using this https://freddysblog.com/2018/12/11/clean-up-after-yourself-docker-your-mom-isnt-here/
I've been using this script for almost two years. It worked well.
After upgrading to Windows 11 version 25H2, it stopped working.

If you are using an insider version of Windows 11, I would try going back to a "stable" version of windows to see if that mitigates your issue.
If that still doesn't help, could you share the logs for that run and the command you are running that is failing.
The current version of Windows 11 is Windows 11 version 25H2, also called the "Windows 11 2025 Update," which was released on September 30, 2025

I haven't been able to repro this so far. Did you try the steps Freddy mentioned in his comment to clean up containers, images and the bccontainerhelper folder? https://freddysblog.com/2018/12/11/clean-up-after-yourself-docker-your-mom-isnt-here/
I haven't used Freddy's script yet. I have a dozen containers for different BC versions generated months ago and they work perfectly. I can't create a new container. If I delete them all, I'm not sure I'll be able to recreate them.
I am facing a similar problem now on my PC upgraded to Windows 11 25H2.
Using this command.
New-BCContainer bc28 -artifactUrl $bcartifacturl -auth NavUserPassword
-Credential $credential -accept_eula
-accept_outdated -accept_insiderEula
-updateHosts -assignPremiumPlan
-doNotCheckHealth -dns 8.8.8.8
-includeAL -isolation hyperv
-useGenericImage "$(Get-BestGenericImageName)-dev" -runSandboxAsOnPrem
-memoryLimit 8G
And this is the output.

If I pull a new OS image it does not help.
Downloading and installing 7019 as we speak - let's see. Will try to create a container afterwards.
I uninstall Docker Desktop 4.50.0 and reinstall 4.49.0 and give it another try and this time, I have created a business central docker container running without problem.
Maybe there is an issue with Docker Desktop 4.50.0?
I don't know about Docker Desktop - I use Docker Engine (which is included in Docker Desktop) Above - the log states 28.5.1 - the latest Docker Engine is 28.5.2 - and that works. I assume that downgrade or upgrade can cleanup the filesystem on your machine - and then it works - I don't think there is a problem with a specific version of Docker. @aholstrup1 - I think you can close this as not repro.
Same issue here, my docker updated to 4.50.0 last night along with a Windows update. Today I can't start existing containers or create new ones with this error: DockerDo : docker: Error response from daemon: hcs::CreateComputeSystem 4245009ca0b6988a0e86cbc896affa5aafda47f34f7c67e251bcd4470298f0de: The container image contains a layer with an unrecognized format.
I got the same problem this morning. Running a full clean as we speak and I get back with a result in an hour.
I removed the container and the Windows images and downloaded them again, it's fine now
Using the good old'e freddy-your-mom-does-not-work-here-ps-script and a reboot got made it work again. Tested it with this
. "$PSScriptRoot\Parameterfile.ps1"
$containerName = 'bc365v24' $password = 'Passw0rd' $securePassword = ConvertTo-SecureString -String $password -AsPlainText -Force $credential = New-Object pscredential 'admin', $securePassword $auth = 'UserPassword'
$shortcutstype = 'DesktopFolder' # None, Desktop or StartMenu $artifactUrl = Get-BcArtifactUrl -type Sandbox -version '24' -country 'dk' -select 'Latest'
New-BcContainer -accept_eula

-auth $auth -artifactUrl $artifactUrl
-dns '1.1.1.1' -updateHosts
-memoryLimit '8G' -alwayspull
-assignpremiumplan -licenseFile $BClicense
Could it be that the parameter -image mcr.microsoft.com/businesscentral:ltsc202x actually does not work as intended?
