Any workaround? My game is already in production and it's supposed to be using a LTS version.

Come on guys, regressions need to be solved ASAP.
This is hurting real projects from real clients, we can't downgrade to the last LTS, get this solved.

It's happening on all 6000.3.5+ versions, included last one 6000.3.9.
And now there is an issue identified with 6000.3.4 version and it's recommended to update to last version.
