If you see the 'Unable to launch your application due to an Internal error. Contact your system administrator' message in Citrix, this is caused by a stuck user Citrix session on one of the Confirm Virtual Desktop Infrastructure (VDA) servers. Your internal IT team can resolve this for you.
Resolve the error
Note down the transaction ID shown in the error message.
Contact your internal IT team and share the transaction ID so they can clear the stuck Citrix session.
đ Note: If your internal IT team are unable to resolve the issue, raise a new case online and include your transaction ID and company name.
