Describe the problem

After a windows sleep cycle the IDE will stop displaying any files and just display the pulsating Arduino logo that is shows when the application is launched. It remains in this state until the Arduino instance is closed. This has only happened when running more than one instance of the IDE, and typically happens to one of the instances.

To reproduce

Start two or more instances of Arduino. Put the computer to sleep. Wake the computer.

Expected behavior

Arduino should work when the computer wakes up.

Arduino IDE version

2.3.6

Operating system

Windows

Operating system version

10

Additional context

This behaviour does not occur all the time. This behaviour is similar to an existing issue where the IDE becomes unresponsive after a sleep cycle (#2148) except that now it isn't even possible to copy and paste unsaved code so if it is the same issue then things are getting worse and worse.
