Connectiv

First day and first time on the support forums. Apologies and thank you. I have, however, been a user of EN (paid) for more years than I can count and more notes than photos on my phone. I recently switched to EN on Safari. I have Mac iOS 11.6 and Safari 15.0. I switched to Safari as the desktop version of EN (direct download) would cause my computer to crash multiple times daily. It started with just EN crashing but progressed to the entire machine. At least, this seems the most reasonable explanation as my computer has stopped crashing after no longer opening and running the desktop version of EN. If the Safari web version doesn't cause the browser to simply crash the tab, I seem to get the attached. Will keep looking for guidance. Appreciate everyone sharing their experiences and suggestions.
