I am running Arduino 2.3.5 on Windows 10 Pro and am running into some strange behavior from the IDE.

When I start the IDE it will open an old/previously opened project (as expected) but if i try to open another .ino file from the file explorer, it will open a new project tab but will open the original project which opened on boot of the IDE, now having two of the same project open.

No matter how many times I try to open a new file, it will just open another instance of the originally booted project.

I did manage to work around this by using the open file option in the IDE, which would then open the expected project as normal, but now even that doesn't work where it will open the originally opened project like mentioned.

Please let me know what other information will be useful.
