PFC200 No Application after reboot

Hello
I have a PFC200 (750-8214) which I have upgraded the firmware to V040601_28.
My problem is that it will not load the application after a reboot.
By switching System (Internal Falsh) it now running the “old” firmware 04.04.03(26).
The problem is the same, application is not loading.
There is no SD-card installed.
I’m using testet in “CODESYS V3.5 SP20 Patch 3” and “CODESYS V3.5 SP20 Patch 4”

I have previous used PFC100 with firmware 04.04.03(26) and CODESYS V3.5 SP20 Patch 3, without any problems.

Wago Codesys add-ons:

What can I do, to fix this?

Edit:
Just to clarify, I can download a application from Codesys, and its will run without any problems, until a reboot.

The fix, in Codesys

The PLC did not have a “Boot application”.
after creating a boot application, everything now working as intended.
