Hello Zoe Royer,
Thanks for reaching Microsoft Community. We apologize for the inconvenience this has caused you. We understand how frustrating it is to see your device crashes very often.
If I may ask, does this issue only happen when using Teams and Zoom meetings? Also, do you have third party antivirus software installed on your device? And what version of Windows your device is running?
In the meantime, you might want to follow the methods on Windows doesn't respond or stops working on Surface (microsoft.com) and observe your device.
Feel free to respond on this thread to keep us posted. Hope to hear from you soon.
Sincerely,
StevenK
