EROFS is read-only error message in Ubuntu snap VSCode when using Apc Customize UI++ extension

I'm current trying to use the Apc Customize UI++ extension on VS Code. Using on Windows It worked perfectly, but on Ubuntu i faced this error:

Apc Extension failed: Error: EROFS: read-only file system, rename '/snap/code/151/usr/share/code/resources/app/out/bootstrap-amd.js' -> '/snap/code/151/usr/share/code/resources/app/out/bootstrap-amd.js.apc.extension.backup'

Could someone save me?

Sorry about bad english, it's not my primary language...

I've tried to Google it so far, but found no response. Looks like nobody uses this extension on Ubuntu.
