I think the source of the crash is an addon that makes chopping trees easier by destroying the whole tree down which wasn't used this time when it crashed, according to my server's content logs (https://mclo.gs/aO5k1nd). In the content logs, it keeps writing errors and that it's a slow-running script. I turned on Holiday Creator Features and Gametest Framework for this addon so it works properly. Here's what my server's logs says about the crash:
Bedrock Edition 1.19.20
