MacBook Pro with BigSur Non Responsive and Fan Running

I recently downloaded Wappler to begin learning to use it. As a I shift between tabs, Wappler doesn’t respond; the only way around it is to quit Wappler and reopen it. It happens every few minutes. Is anyone experiencing similar behavior? Thank you!
