Describe the problem

I am experiencing a recurring issue with Arduino IDE version 2.3.5 on my Windows system. Specifically, when I double-click on a .ino file to open it, the IDE always opens the previously opened sketch instead of the newly selected file.

To reproduce

• Steps to reproduce:- Open Arduino IDE and load file A (fileA.ino).

• Leave file A open.

• Double-click on file B (fileB.ino) in the file explorer to open it.

• Observe that instead of file B, the IDE reopens file A.

• Observed behavior:

• • A new IDE window briefly appears but closes immediately, leaving the old sketch (file A) opened instead of file B.

• This happens consistently regardless of the .ino file selected.

• Additional notes:

• • My Task Manager shows multiple Arduino-related processes running (around 10), which seems unusual compared to other systems where fewer processes are observed.

• I’ve tried reinstalling the IDE, resetting preferences, clearing temporary files, and even manually opening files using the IDE menu, but the issue persists.

• I am using the latest version of the IDE from the official Arduino website.

Expected behavior

Please investigate if this is a bug related to file management, task handling, or process conflicts in the IDE.
