Error message when using nRF Connect for desktop with multiple apps: Error while updated nrfutil core

Hello,

I am using nRF Connect SDK v2.6.1 and nRF Connect for desktop v5.0.2.

I am currently developing with the nRF21540 and for some tests, I want to use the RSSI Viewer, Bluetooth Low Energy, and Direct Test Mode. However, I always receive the following error message when opening them. Does anyone have any tips or hints on how I can solve this?

08:53:45.670 Error: Failed with exit code 1. The process cannot access the file because it is being used by another process. (os error 32).
08:53:45.670 Error while updated nrfutil core
Thank you in advance!
