I was in the middle of editing a wedding session, when all of the sudden the images start to appear totally different from the original RAW file. When I started editing the Gallery everything was fine. Then after some time I realised, that the programm makes some images appear way brighter then the original RAW files. I didn't change anything or imported them with a preset. They sometimes look just like the shot RAW picture in the Library but look totally different in the Development section. I can't reset this "editing" made by the program. Also the Preview Image on the left side appears right in the first second but then switches.
I am using a Canon EOS R and never had any problems with my files.
Does anyone know where this weird "editing" comes from and how I can get my original original RAW file look back? It is really frustrating to see the original Image being made way brighter, then intended.

As you can tell the navigator image also changed to the overexposed version. The original Raw file is not that overexposed and looks like on the navigator image in the initial screenshot.
The histogram for the image displayed indicates that the image IS dramatically overexposed. That is why Lightroom displays it as it does. That is why there are adjustment tools in Lightroom to make corrections as needed. Lightroom is not capable of reading in-camera settings. If you want to take the time to establish default settings for your cameras, that will help improve initial display your images. However, you must expect to make adjustments using the Lightroom tools in order to optimize the quality of your images. That's what Lightroom is for.
The image was not taken overexposed. It was taken as it shows on the left side. Lightroom changes it up after a few seconds in the development section. As you can see on the left side (Navigator) the whites are not burned out and the overall color is less yellow. I know there exist Camera profiles but that doesn't fix the overexposing, that lightroom applies to the image.
I know what Lightroom is for and I've never had any problems with my RAW images. I don't use any in camera setting for exposure or special color profiles. Half of this session works just fine and lighroom shows me this exact RAW image in the development section but the other half gets overexposed by the program.

Lightroom Classic can't show the user anything about exposure (an attribute that takes place solely at capture) from the Histogram or otherwise; you need a raw Histogram for that. Lightroom Classic is showing the current rendering is too bright and that's why the Histogram looks that way.
You have Embedded & Sidecar selected in the Import module File Handling> Build Previews selected. This uses the camera embedded JPEG preview until you either apply a Develop setting or build Previews in the Library module. The double-arrow icon on the thumbnail indicates the Embeded & Sidecar preview is still active and LrC Previews have not been built. You may have an in-camera setting that LrC can not apply that is causing the issue. If you upload one of the files to Dropbox or other file sharing site we can see if that's what's causing the issue.
