WSL Permission denied whenever I try to open up sage-starter theme (Windows)

# The stream or file "/app/bedrock/web/app/cache/acorn/logs/application.log" could not be opened in append mode: Failed to open stream: Permission denied

I always seem to get an error whenever trying to access the theme FE. Already granted full permision on WSL, added acorn.
Project is running from a Ubuntu sub-system within a docker container + bedrock. Non-blade themes such as the vanilla WP themes work without any problems at all

Can you go into the running PHP-FPM Docker container in a shell (akin to docker exec -ti [...] sh) and try to create a file at /app/bedrock/web/app/cache/acorn/framework/views/065a2e8109a98ebbf859445720bc335ea8db6e19.php?
Any errors? Also, from the perspective of the Docker container, are ownership and permissions correct?
