With versions 5.2, 8.0.4 and 12.3.1 on Windows 10 x64 I get the same result:

I can confirm that this bug also occurs on 13.0.0 for Linux (64-bit), see this attached screenshot:

Hey guys,

*2 things:

  • 1) not everything is a BUG, I myself fell into a lot of traps in Return problems when I create functions in WL, due to lack of training thro documentation (my fault), but (I believe that) nothing about this command has changed in recent years.. I recommend testing through the Documentation!

  • 2) Wolfram's QA (quality assurance) is the best of the best developers, they are amazing! ..for me, Return is working correctly in 13.1, I don't know if something has changed internally, because I didn't identify it..

..regarding the inconsistency between Cloud and Mathematica, I believe a ticket has already been made..

Thanks!
