There are a lot of reports of crashes and other problems on Ryzen systems with integrated Radeon graphics lately. Search the forum and you’ll find them. If you’ve tried installing the latest Radeon driver downloaded from AMD (not from Microsoft) and turned off video screenshots in Zwift settings, you may not be able to use that laptop until they fix it. There hasn’t been any public acknowledgement of the problem but it’s affecting a lot of people and it’s clear that they know about it.
