@cortinico suggest merging then releasing 1.20.1.

I'll open a new issue that covers the actual root cause, and we can look to a more appropriate solution for ensuring the correct compiler version is used by detekt and cannot be overridden.

Edit: Opened #4817

[cortinico]

Just want to cross check with everyone that we cosnider this worth publishing a point release.

@3flex Think will land in 1.21 as I don't think we need to do a point release just for this. Please let me know if this is not the case.
