Jumping in here because I'm encountring the same issue
So, I switched from Retropie today but I'm having a huge hiccup.
I run my Raspberry Pi 4 with 2 DragonRise encoders. The Pie 4 HATES them and always causes issues. Back on RetroPie I just edit the /boot/config.txt and add the following:
usbhid.quirks=0x0079:0x0006:0x00000400
This used to do the trick and never had any issues after adding the line.
Now with Recalbox I noticed the same issue I had with RetroPie so I added the line to /boot/config.txt, sadly that didn't fix it.
The issue to be exact is when booting Recalbox, I notice a stutter every second during the boot animation. After it boots successfully, the UI is just frozen with a stuck notification on the top right that still hasn't reached the top stating that the controller is unplugged.

Adding to that, I noticed a new weird behavior. After a minute or two, Recalbox restarts and both controllers work fine. Sometimes it takes over 5 minutes.
Moreover, If one encoder is connected I don't have any issues.
