Windows 10: Microsoft Apps Crashing

Why are the Microsoft Apps crashing? I am trying upload pictures from my computer but the app will not stay open long enough for me to do so. Also, my Microsoft Store will not load before crashing. I have reset the app and it is still crashing. I don't want to reset my photos because I do not want to risk losing them. What do I do?

all games crash!

I suggest you run rthdribl > http://www.daionet.gr.jp/~masa/archives/rthdribl_1_2.zip
Increase the window size step by step and watch your vga temps permanently.
What happens?
If it crashes, run at stock speeds as suggested before and retry.

P.S.: When your system locks, does the display signal turn off after a time?
Stuttering sound or no sound at all when freezing?
What X1800XT model do you own exactly?

ive watch my temps and both the cpu and gpu are within normal ranges. when it freezes it simply freezes the image and stops the sound. i must reboot to get back to windows.

 

Windows Photos App crashes


So since today my Photos App is crashing as soon as i open it. It goes into a blackscreen for about 2-3 Seconds and than crashes.

Information about the error:
This Crash is generating chrash dumps that contain the error code 0xC0000602 in module mrt100_app.dll or 0xc000027b in module twinapi.appcore.dll.

I found two intresting facts about the error:
- If I try a system restore to a point created 3 days ago, the App starts working again. A few minutes after using the system, the app starts crashing again.
- I created a new local account and the app does seem to work on that new account until now.

Steps I have tried:
- Reinstall Photos app by uninstalling it using Powershell and rerisntalling it - did not change anything
- Reregister the App - did not change anything
- Scan the System with sfc and dism - no errors
- Use System resstore - see above, did only work for a few minutes.

Microsoft Support suggested reinstalling Windows, but I do non really want to reinstall the whole system just because one app is not working...
