RaspberryMatic becomes unresponsive after adding a program and restarting

[UllisHellfireeXperiments]

Describe the issue you are experiencing

I am using RaspberryMatic (HA Add-on) for a few years now, operating thermostats (HM-CC-RT-DN), a few other devices (HM-PB-2-WM55, HM-WDS10-TH-O, HM-WDS40-TH-I-2) and a few programs without any issues up to now.

However, I recently added a few additional devices, updated the existing programs and added new programs. At first RaspberryMatic continued to work properly, however, after the update to 3.76.6 the UI became unresponsive. Opening RaspberryMatic from the Home Assistant UI revealed the RaspberryMatic Home Page as usual, but clicking on anything made it unresponsive. Deactivating Home Assistant's Watchdog function even made Home Assistant unresponsive for several minutes.

Of course, at first I thought that the issue had something to do with the update. But, after restoring a backup, adding the new devices and programs - but not performing the update - it turned out that a restart a again lead to RaspberryMatic becoming unresponsive.

So I again restored a backup, but performed the update to 3.76.6 first. The update did not pose any problems.

Next I recreated what I had done before step by step with a backup and reboot between each step. It turned out that the critical action was adding a new program. The new program was simply triggered by a system state being updated and set all the thermostats to a certain temperature. As I said before, the issue was latent until after the next restart.

It might be noteworthy, that adding an empty program did not trigger the issue. Adding a condition and actions in the next step did.

Describe the behavior you expected

RaspberryMatic shall operate normally after adding new programs. In case of a corrupt or in any other way invalid program I would expect an error message and graceful degradation.

Steps to reproduce the issue

1. Add a new program.
2. Reboot.

Anything in the logs that might be useful for us?

Unfortunately I was not able to review any logs because of the UI being unresponsive.
