Minecraft Bedrock constantly crashes when running any of MakeCode tutorials in it

Just bought Minecraft Bedrock for PC, running on Windows 10 with all latest updates, latest Minecraft version 1.16.201, downloaded latest CodeConnection.

• Start CodeConnection, start Minecraft, execute "/connect 192.168.1.153:19131" in Minecraft chat, connects ok
• click any tutorial in CodeConnection (e.g. "Flower Trail"), use MakeCode/Blocks language, put the simple code for tutorial and click Play button (triangle)
• go to Minecraft and try to use the code from the tutorial
• it will run for ~30 seconds and then Minecraft crashes and closes silently. Every time, no exclusions. Tutorials that don't continuously execute code (e.g. a 1-time action call) - may work (if they run shorter than ~30sec)
