in case of endless loops ..... next to no way back since STOP button hidden

[commentsonly]

From time to time miseries do happen (limited brain) which result in an endless loop within node-red
For example endless lines of type
"14 Oct 13:19:33 - [warn] [function:controller] 11152287=NaN"
rolling in one after other wihin nanosconds.

One feels happy in the first place when realising one's still able to reach
Settings>Addons>node-red>Info

but the culprit is ... there's only a "uninstall" Button shown ... the most important one "stop" is hidden as is "restart" or "open web".

So my current way to get such things solved is
move the flows.json from the smb share>addon_configs>xxxxx_nodered
into a save place
reboot the complete HA
start node-red
import the flows from previously saved file
and correct the last known modifications made so it works again.

Any idea about why the STOP button is hidden? I would make live much easier if in any case one's entitled to stop the whole lot.
It'll surely not help around the problem one must remove and reimport the flows.json, since a simple stop won't cure the issues in there itself, but it would not ask for a complete reboot of HA itself.
