TypeScript Error When Using `@effect/schema` with `fast-check`

I'm trying to use @effect/schema@0.64.20's Arbitrary with fast-check@3.13.2 (tested with latest v too) and I get the following TS error:
Argument of type 'typeof import("/node_modules/.pnpm/fast-check@3.13.2/node_modules/fast-check/lib/esm/types/fast-check", { with: { "resolution-mode": "import" } })' is not assignable to parameter of type 'typeof import("/node_modules/.pnpm/fast-check@3.13.2/node_modules/fast-check/lib/types/fast-check")'.
           // snip
                  Types of parameters 'mrng' and 'mrng' are incompatible.
                    Type 'import("/node_modules/.pnpm/fast-check@3.13.2/node_modules/fast-check/lib/esm/types/random/generator/Random", { with: { "resolution-mode": "import" } }).Random' is not assignable to type 'import("/node_modules/.pnpm/fast-check@3.13.2/node_modules/fast-check/lib/types/random/generator/Random").Random'.ts(2345)

It seems an ESM problem and I have no idea where to start to understand where the problem could lies
