> I have tried accessing the variables from the trigger run function
multiple times after multiple context switches in event loop. I can access the
variable values without any issues
Yes. Accessing will work. But the fact that you can do it - does not mean
you should :).
The problem is that if you do it during the event loop, the access (if not
using async/await) will block - in I/O or networking and when it is blocked, no
other triggers are running because event loop runs synchronously. See what
happens (and warnings you get) when you just "sleep()" for a second or so. Or
give your Triggered fractional CPU (say 0.05) - then you will see that even
short - 50ms blocking operation will be disastrous for the event loop.
