No available data and PLC program gone after reboot

I got a call from our customer that the machine suddenly stopped. when going online i saw the following dashboard. all data was unavailable.

I rebooted the core and all app started exept for the PLC. I tried to go online but i got the notification that the was no application in the core. Luckily i have the back-up but how can it be that my entire PLC program was gone?!

while creating the system report I got a couple of errors see 'protocol.png'

Note: I Got the call around 2023-06-28 12:40, maybe that it helps searching for the error. The customer has cycled the power of the main cabinet before calling, so some data may be lost.

Hello EngJay,
the behaviour confirmed by you above ( bootproject gone, by renaming ) had been monitored, analyzed and fixed.
Please continue with the upcoming 1.20 LTS version coming up beginning of August. 

Thanks and Bye
