I've had this issue for a while, and I haven't found a solution to fix it for good. When I start up Reaper with my UMC404HD plugged in, Reaper starts getting buggy, slow, and stops responding to my input.
The only way to fix this issue has been to do the following procedure:
1) Unplug interface
2) Click Reaper -> Settings -> Audio -> Device -> check/uncheck "Allow projects to override device sample rate" -> Apply -> OK
3) Plug interface back in
This procedure has always worked, but I'm really tired of having to do this every time I want to record mics/instruments into Reaper. What is the solution to fix this annoying issue with the sample rates?
I tried to get help on the reaper subreddit, but I was told that the issue is with my Mac. I went to the Behringer site, but all of the drivers are for Windows computers. There are none available for MacOS.

The interface worked flawlessly for a long time with my computer and never gave me these kinds of issues. I don't know what changed, but one day, I had started having this problem, and it's persisted until present day.
I went to Audio Midi Setup on my mac. The UMC404HD is set to "2 ch 16-bit Integer 48.0 kHz"
The MacBook speakers are set to 48000Hz 2 ch 32-bit float, and the MacBook microphone is set to 48000Hz 1 ch 32-bit float. I don't see why either would matter since I don't use the microphone or speakers for recording. However, I have a feeling that's not where the problem is.
Is there a solution, or am I doomed to have to go through the procedure I outlined above every time I open reaper while using my UMC404HD?
Thank you all in advance for any help. I've tried the Reaper subreddit and the compatibility forum, and I haven't found a resolution to this problem. I'm just a little frustrated and discouraged right now.
