What happened?

The problem occurs every time I leave hop-gui unused for a while. If it remains open without use, then when I try to edit any action or create a new pipeline, nothing happens. The only solution is to restart hop-gui, and when I close it, it throws the following error in the cmd.

"Serious error detected in the Hop GUI: Failed to execute runnable (org.eclipse.swt.SWTException: Widget is disposed) org.eclipse.swt.SWTException: Failed to execute runnable (org.eclipse.swt.SWTException: Widget is disposed) at org.eclipse.swt.SWT.error(SWT.java:4918) at org.eclipse.swt.SWT.error(SWT.java:4833) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:135) at org.eclipse.swt.widgets.Display.runAsyncMessages(Display.java:4029) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3645) at org.eclipse.swt.widgets.Display.release(Display.java:3720) at org.eclipse.swt.graphics.Device.dispose(Device.java:324) at org.apache.hop.ui.hopgui.HopGui.open(HopGui.java:488) at org.apache.hop.ui.hopgui.HopGui.main(HopGui.java:352) Suppressed: org.eclipse.swt.SWTException: Failed to execute runnable (org.eclipse.swt.SWTException: Widget is disposed) ... 9 more Caused by: org.eclipse.swt.SWTException: Widget is disposed at org.eclipse.swt.SWT.error(SWT.java:4918) at org.eclipse.swt.SWT.error(SWT.java:4833) at org.eclipse.swt.SWT.error(SWT.java:4804) at org.eclipse.swt.widgets.Widget.error(Widget.java:450) at org.eclipse.swt.widgets.Widget.checkWidget(Widget.java:369) at org.eclipse.swt.widgets.Dialog.checkParent(Dialog.java:169) at org.eclipse.swt.widgets.Dialog.(Dialog.java:131) at org.apache.hop.ui.core.dialog.ErrorDialog.(ErrorDialog.java:78) at org.apache.hop.ui.hopgui.context.GuiContextUtil.lambda$handleActionSelection$0(GuiContextUtil.java:184) at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:40) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:132) ... 6 more Suppressed: org.eclipse.swt.SWTException: Failed to execute runnable (org.eclipse.swt.SWTException: Widget is disposed) ... 9 more Caused by: org.eclipse.swt.SWTException: Widget is disposed at org.eclipse.swt.SWT.error(SWT.java:4918) at org.eclipse.swt.SWT.error(SWT.java:4833) at org.eclipse.swt.SWT.error(SWT.java:4804) at org.eclipse.swt.widgets.Widget.error(Widget.java:450) at org.eclipse.swt.widgets.Widget.checkWidget(Widget.java:369) at org.eclipse.swt.widgets.Dialog.checkParent(Dialog.java:169) at org.eclipse.swt.widgets.Dialog.(Dialog.java:131) at org.apache.hop.ui.core.dialog.ErrorDialog.(ErrorDialog.java:78) at org.apache.hop.ui.hopgui.context.GuiContextUtil.lambda$handleActionSelection$0(GuiContextUtil.java:184) at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:40) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:132) ... 6 more Caused by: org.eclipse.swt.SWTException: Widget is disposed at org.eclipse.swt.SWT.error(SWT.java:4918) at org.eclipse.swt.SWT.error(SWT.java:4833) at org.eclipse.swt.SWT.error(SWT.java:4804) at org.eclipse.swt.widgets.Widget.error(Widget.java:450) at org.eclipse.swt.widgets.Widget.checkWidget(Widget.java:369) at org.eclipse.swt.widgets.Dialog.checkParent(Dialog.java:169) at org.eclipse.swt.widgets.Dialog.(Dialog.java:131) at org.apache.hop.ui.core.dialog.ErrorDialog.(ErrorDialog.java:78) at org.apache.hop.ui.hopgui.context.GuiContextUtil.lambda$handleActionSelection$0(GuiContextUtil.java:184) at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:40) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:132) ... 6 more
