This is a similar issue to all the recent errors around creating files on Positron Web #4893.

This line is where we construct the projectRoot from a file system path, which we won't be able to access on Web.

positron/src/vs/workbench/services/positronNewProject/common/positronNewProjectService.ts

Line 330 in 0931e85

const projectRoot = URI.file(this._newProjectConfig?.projectFolder!);

CC @timtmok for awareness: this looks like another Web file path situation
