It's great that you have attached the logs. I looked into it and could not find anything useful in it due to a bug:

2023-12-21 13:30:51 2023-12-21T05:30:51.512Z root ERROR Failed to start the backend application:

The good news is that it has been fixed (#2236). If you want to help us, please get the nightly IDE build with the logging fixes from here: https://www.arduino.cc/en/software#nightly-builds.

Start the IDE (it won't start), get the logs, and attach them again to this issue. Then, we will see what the problem is.

The nightly build does not have the fix for your startup issue, but we will hopefully see the cause of the issue.

Thanks

Thank you for your reply. I ran nightly buildings and did provide me with more information,

Here's the problem:

I don't know what caused it, but I successfully launched the GUI by adding line '127.0.0.1 localhost' to the system hosts.
