Hi @kaffgee Have you checked your permissions to see all is ok there/ Apps-Camera-Permissions. Are on you the latest camera update and are you able to Reset the camera, via Settings- Reset Settings in the app. An idea to Force stop via Apps-Camera and then clear cache via storage-Clear Data and cache.
could also try in Safe Mode: https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/
if ok there would pinpoint recent 3rd party apps which have been installed (if applicable)
If no resolution advisable to wipe the cache partition to clear temporary files, data is intact.
1. Turn off the device.
2. Connect To Computer or plug in USB-C Headphones , Press and hold the Volume Up key and then press and hold the Power key
3. When the Android logo displays, release all three keys.
4. An 'Installing system update' message will show for 30 - 60 seconds before the Android system recovery menu options appear.
5. Press the Volume down key several times to highlight wipe cache partition.
6. Press Power key to select.
7. Press the Volume down key to highlight yes, them and press the Power key to select.
8. When the wipe cache partition is complete, Reboot system now is highlighted.
9. Press the Power key to restart the device.
can also repair apps via the same Recovery Menu.
If there are still issues check the Diagnostics to see if any errors are identified. Go to Samsung Members-Support-Diagnostics-Camera. You may need to send Error Report: Samsung Members-Support-Send Feedback-Camera. Detail the issues and ensure that the system logs are attached.
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
