PENDING Powershell Menu during OSD missing?

[TheWookie]

Hi everyone,
I hope someone can help?
We have 3 'options' during our OSD process where 2 have stopped working? The 1 which works is a prompt to enter the PC name and a based on a VB Script. The 2 which are failing are drop down menus for language packs and fonts., these are both powershell scripts.
We've recently upgraded our SCCM environment to 1806, and although I can't confirm, these PS menus were definitely working before the upgrade, but noticed the issue after. I've checked the boot image 'optional components' and I have the Windows Powershell (winPE-DismCmdlets) & (WinPE-Powershell), Microsoft .NET (WinPE-NetFx) added.
The task sequence steps haven't changed and are command line steps are cmd /c powershell -ExecutionPolicy Bypass -File selectlanguage.ps1

Would the upgrade have reset 'stuff' as it looks to have an issue with the PS scripts, so I'm pretty sure I just need to enable something, but can't think what?

P.S. the smsts.log file doesn't show any errors, and you can see the TS steps show/pause when the 'menu' should appear, then carries on?

Thanks
Steve

I have seen this even with my setup, we have a custom HTA that loads after we select the TS. Whenever any change is made to HTA in the backend, i ensure i redistribute the boot image and the packages that are related to HTA.

You mentioned that 2 options are failing, are you able to see the drop down menus during the OSD ?.

Hi Prajwal,
We didn't go down the HTA route, just a pure PS script. Yes, the 2 options which are failing, we aren't able to see the menus.

OK, I'm a bit further. I spotted an error flash up saying 'unable to load xmlreader', any idea's?
