Outlook crashes when forwarding/replying /resending any message

Hi,

When trying to send or reply to a new e-mail in the Outlook application, Outlook did stop its activation. There is no problem in the office 365 applications we use throughout the company,Our problem is in licensed Office 2013 and Office 2016 applications, the problem is caused by the signature, there are no problems for users who do not have a signature.

Solutions which I tried;
I removed the plugins
I removed the com plugins
Office Repair done
Outlook.exe /safe tried

Tried solution on Microsoft's website
Antivirus app removed
All office updates are done
Uninstalled and reinstalled all office application

However the problem is not solved.

Could you help me about this problem?
