I’m pretty certain that 3.29 will work.
This post: Recording 4 channels: Behringer Uphoria UMC404HD [SOLVED] is from 2018 - the driver in use then was probably 3.29 which was dated 2015. The OP’s device info shown by Audacity was:

This post outlines the identical problem: Reddit - Dive into anything
As does this: Behringer UMC404HD 4-track recording [SOLVED] (The user helpfully says
“I can confirm it works. The 3.29 driver is available through their website if you know the file name (…) and it immediately gave me 4 channels of recording with WASAPI and thus Audacity (2.33 on W10). Thank you!”
but didn’t give a URL for the download. I’ve added a support ticket to Behringer’s support portal but I’m not hopeful.

After some more research, it looks like the newer driver from Behringer (4.38) is the problem and no longer supports 4 simultaneous channel recording. The old driver (3.29) does. I think you can still find the old driver online, but doesn’t look like Behringer provides it. Not sure if they will fix this issue in a coming release. But the old driver works great if you can get it.
And I don’t know if this issue only affects Audacity. I’ve read where you can just use the ASIO driver in other programs like Reaper.
This post: Reddit - Dive into anything discusses incompatibility between GPL and ASIO license:

I assume this is in Windows? Audacity, for legal reasons, is incompatible with ASIO drivers. The free license Steinberg releases ASIO under is incompatible with Audacity’s GPL license. It falls back to the standard Windows stereo drivers. Audacity will work fine with all four channels on Mac or Linux.

Almost all commercial software will work with the UMC’s ASIO drivers. A free option to record is OcenAudio
