Greetings alex23,
I'm sorry to hear that your EOS R50 camera is having this blackout issue when using the camera. Let's check to see if the issue may be related to an accessory or attachment on the camera. First, let's test to see if using a different memory card will resolve this issue. Prior to taking photos on a different card, please format it within the camera. Please note that formatting a card will erase all data from the card. In case this works, then it tells us that the prior memory card may have been malfunctioning which causes the camera to lock up.
If the camera continues to have this blackout issue when using another card, then see if you can test a different lens with the camera. Please also clean the contacts with the current lens you're using to ensure that there is proper communication between the camera and the lens. You may use a dry microfiber cloth to wipe the lens contacts.
I would also suggest disconnecting or removing any other attachment that is attached to the camera to see if an accessory was the cause of this issue. If the issue persists, then we would suggest on sending the camera to our facility for repair.
