Skyrim crashes with no error message?

My skyrim keeps crashing after completing the quest "daedra's best friend". I had it on steam because it happened first, I deleted both the game and steam and then reloaded it. It is pointless. Then I got it on my computer via the xbox app (gamepass ultimate) this is about the special edition of skyrim. It also happens all the time here. What else can I do?

Standard procedure for all bugs.

Instead of reinstalling, you do a file repair. You also install a program to monitor the temperature of the CPU (e.g. Core-Temp) and GPU.

Before you do the file repair, uninstall all mods and then leave them out afterwards.

Where exactly is the game crashing? And without an error message? I'm assuming that you play without mods, that means it can't really be because of that. Did you really delete all files when you uninstalled the game? If you just click "Uninstall" on Steam, not all files will be removed. In addition, all files subsequently added by mods are retained. Do you only have the problem with this savegame? You probably won't have any other savegame to test this with, will you?

Moin, this is already the second game status that I have this with and I no longer get the game via the xbox app on the pc via steam. I don't use mods. It just goes out after the quest is over.

How do I do a file repair?

What does that mean after completing the quest? As soon as the message appears? Or not until the next loading screen?

You can find the instructions for a file repair faster than I could write them.

As soon as the message "completed" appears

Hm… A really crazy idea: try changing the game to English and try again. I don't know if that works and if so why, but otherwise I wouldn't think of anything.
