FP3 system apps crash when turning off airplane mode

Hello Forum, I hope I can still get some support with this old model.
Every time I turn off airplane mode (so my phone starts connecting to network and wifi) my phone gets very slow. I had this problem for a while so I reset my phone in december but the problem returned instantly after the reset.
The phone doesn’t only get slow, but most of the times some app gets unresponsive. This is most often a system app like system UI, but sometimes also a third party app (whatsapp or chromium based browser). I keep getting the alert that the app is unresponsive untill I choose to kill the app.
This is very annoying, since sometimes you just need your phone asap, but this is preventing me from using it quickly.

Do more people with FP(3) struggle with this issue?
Is there something I can do to further analyse the issue to find a solution? Is there a solution or should I upgrade to fp5 (kind of beats the purpose of buying an FP in the first place)?

Is the behaviour the same when you just enable Wi-Fi while still in airplane mode?

Is the behaviour the same when you remove the SIM card from the phone?

Good question.
I tried turning on wifi first this morning and for a few seconds I thought the phone was only a bit slow, but then System-UI stopped responding and had to be restarted.

i will try turning off flight mode with wifi turned off later today.
