Pycom browser-IDE not working

[David-Prime]

The browser-IDE isn't working properly anymore.
The REPL isn't working and the change in the micropython code is on another place than the marker, which makes it extremely hard to correct the code.

I'm running a LoPy4 with firmware 1.20.2.r6, and it worked fine until approx. one week ago, bothe browser-IDE at pybytes.com and the local IDE:s Atom and VS Code by both COM and WiFi, but now notheing of this works properly. Atom and VS Code doesn't even connects. The LoPy4 does connect to my pulse-belt and sending data to pybytes by BLE/WiFi/MQTT, but reaches exeptions at sertain operations. But because I experience these issues I can't correct the code to solve these issues either. What could be the cause, and how can I solve this problem?
