Erro = System.NullReferenceException

Hello community,

Every time I try to start a NEW flow or EDIT an existing flow this error message appears.

I have already reinstalled the PAD, restarted the machine and this error persists.

Does anyone have any ideas?

 

"Message = Object reference not defined for an instance of an object.

Where did you guys find the installer for 2.39? 
I went to the following link but couldnt find the installer: 

https://learn.microsoft.com/en-us/power-platform/released-versions/power-automate-desktop/2312


Your help would really be appreciated!

Hi, I dont find the link to download the previous version. Could you write me the link, please?

Thanks in advance. 😉

Hi @alrofe 

I basically reached out to Microsoft Support they provided the link to download the software. This was the link that was given to me.

The downgrade doesn't work for me. Problem still occurs.

Por si ayuda en Algo, esta novedad me ocurrió al instalar el Power automate en una máquina que me entregaron puntualmente en la propia sesión del Administrador de dicha máquina, Entonces lo que me funcionó fue Crear una Sesión nueva en esa máquina (La incluí en el grupo de administradores) intenté abrir desde esta nueva sesión y continuo el Error, por lo que opté por Desinstalar el Power automate desde esta sesión Nueva para todas las sesiones e instalé la versión 2.39.306.23341, obviamente al abrir no le di en actualizar y Listo Problema Solucionado.

yes it doesn't work anymore. I think it's an incompatible operating system problem.

I've noticed that Visual Basic for Applications (VBA) for Word and Excel also gets strange system errors when running Power Automate Desktop (PAD). Sometimes, I can't even load or save my macro-enabled Excel spreadsheets. I must restart my PC after using PAD to reduce the toxic contamination.

Hi,

 

I had the same problem, and I managed to solve it after doing the pending Windows updates.

Downgrading the version would not solve the problem in my case, as the flows had already been changed in version 2.42.

 

For Information, these were the updates made:

Update for Windows Server 2019 (KB5034127)
Update for .NET Framework 3.5, 4.7.2 and 4.8 (KB5034273)

I believe it was the .NET update that resolved the problem.
