[b3hni4]

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest released version
• Search the existing issues.
• Refer to the FAQ.
• Refer to Differences between Windows PowerShell 5.1 and PowerShell.

Steps to reproduce

This only happens with POST requests to the same uri (GET request works as intended)

$serviceUsername = 'XXX'
$serviceUserPassword = Read-Host -AsSecureString
$cred = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $serviceUsername, $serviceUserPassword
$body = @{foo = "foo"}
$parameters = @{
          Uri         = "https://xxx.net"
          METHOD      = "POST"
          Credential  = $cred
          Body        = $body | ConvertTo-Json 
          ContentType = 'application/json'
      }
$response = Invoke-WebRequest @parameters

pwsh(66802,0x70000453e000) malloc: *** error for object 0x600002bdef20: pointer being freed was not allocated
pwsh(66802,0x70000453e000) malloc: *** set a breakpoint in malloc_error_break to debug
Abort trap: 6

This does not happen in version 7.3.12

Expected behavior

Web request returns as expected.

Actual behavior

Shell crashes.

Error details

Need more specific steps that repro to be able to debug this. The malloc should be happening within .NET runtime and not within the cmdlet. A simple scenario like invoke-webrequest -uri 'https://httpbin.org/post' -Method Post -Body @{foo='bar'} works.
