The only quite not fitting app on your system is the IDE 1.18.7. There it could be that is trying to acces interfaces not existing on the used apps like ctrlX MOTION 1.12.8, CTRLX CORE Python runtime 1.12.4 and ctrlX AutomationCore 1.12.8.
The only problem that I know that gets device get slow and at some point unreachable is 100% filled up internal RAM or flash storage. Are there e.g. files writiten via Node-RED? Could you do a reboot of the control and afterwards have a look to the CPU and storage utilisation?
You can restart the ctrlX CORE even via its web UI (not needing any ssh connection). See this post if it it is really necessary to get ssh access to your control.
