Crash on Windows 10

I am on Windows 10. A week after I installed Minecraft Bedrock: Windows 10, nothing happened, I can play with my friends and everything were well.

But after that, every time I opened Minecraft Bedrock: Windows 10, my game always crashed. My computer slowed down drastically. I even cannot move my cursor. I have to restart my computer with the power button (because Ctrl+Alt+Del doesn't work) to work normally.

Please fix this crash, these are my computer information:

Edition: Windows 10 Home Single Language.

System Type: 64-bit operating system, x64-based processor

Processor: AMD A4-9120 RADEON R3, 4 COMPUTE CORES      2C+2G       2.20 GHz

Thank you.
