SWT Exception while creating new project in 5.10

hi i updated my katalon version this morning and when i tried to refresh the existing project i got “Error in Building Workspace” and when i tried to create a new project i got “Failed to execute runnable (java.lang.OutOfMemoryError: unable to create new native thread)”
can some one help me in solving this

Could you try closing the Tool and reopen it again?

thanks for the reply Brain, but i have tried reopening and even tried reinstalling the katalon and also i have tried clearing my temp folder too
