[DUPLICATE] Cubasis 3 crashes when in bkg

A user on the Audiobus forum brought this up and I can confirm.
Steps:
Open Cubasis
Create a new empty project
Add a MIDI track
Switch to an AU instrument
Open the UI for the instrument
Switch to another app, leaving Cubasis in the background
Cubasis crashes within 15 seconds (red mic icon disappears)
Additional details:
The crash doesn’t happen if I don’t switch to another app
The crash doesn’t happen if background audio is disabled
The crash doesn’t happen if the AU UI is minimized when Cubasis is moved to the background
The crash happens with or without “Studio quality” enabled
The crash happens whether the device is being charged or not
The crash happens with or without external audio interfaces plugged in
The crash doesn’t happen with built-in instruments or effects
The crash also happens with AU effects
The crash happens with multiple vendors (I tried Nikolozi, Burns Audio, Audio Damage, ToneBoosters and others)
The crash doesn’t happen with AUM or NanoStudio 2 using comparable steps
The crash happens in iPadOS 14.0 (iPad Pro 12.9" 3rd gen), iPadOS 13.7 (iPad 5th gen) and iOS 14.0 (iPhone XR)
The crash logs all say some variation of “9 seconds cpu time over 11 second (84% cpu average), exceeding limit of 60% cpu over 15 seconds”
