Given that Workbench is used extensively internally to Wolfram Research (various personal communications over the years), it is highly likely that there is a version of Workbench somewhere that works with 12.2.
I would not hold my breath that it would be 'native' on Apple Silicon, but it should work under Rosetta II, assuming that Eclipse does.
Possibly, someone at Wolfram will see these posts, and find the right people to release an update "for the rest of us".
