Rollup 'is not exported' error prevents me from taking a build

Question

I'm a novice at bundling tools and give a start with Rollup because we use it in corp. But when I want to build, it greets me with the following error:

yarn run v1.22.17
$ rimraf dist && tsc && rollup -c rollup.config.js

./out-tsc/unit/index.js → dist...

I'm on verge of going nuts. Because the website Rollup redirects me has nothing about it contrarily to what it claims to have. Could you help me to fix this issue? I don't think anything is wrong with config files, nevertheless, I shared them in the following if you want to check.
