runing as normal user gives this error:

Have exact same issue here, but sometimes it's OK. Pretty weird as similar code like below doesn't trigger this error:
$DriveLetter = $DriveLetter + ":"
BTW, it's better to stop the script if error occurs, otherwise getting unexpected results.

Found the root cause:

param (
[ValidatePattern('^[c-zC-Z]$')]
[string]$ScratchDisk
)

The ValidatePattern is limiting the $ScratchDisk to a single letter from c-z or C-Z. Assigning to anything else causes the failure.
