In recent insider builds, lots of desktop apps crashes upon saving a file or browse for a file. The error is something as below

Unhandled exception at 0x00007FFA166E134D (shell32.dll) in Xamarin Workbooks.exe: 0xC0000005: Access violation writing location 0xFFFFFFFFFFFFFF8B.

Now I am using the Build 15063.14 with latest updates. This is really really frustrating as I cannot attach a file as attachment in outlook.com with Google Chrome or save a workbook in Xamarin Workbooks.

This error happens on both my machines which both run insider builds

  • Sounds like a bug in Xamarin. Have you tried uninstalling it? – DavidPostill Apr 06 '17 at 12:43
  • the tool accesses a NULL pointer. this is a bug in tools. report it to developers. – magicandre1981 Apr 06 '17 at 16:12
  • No, it's not an issue with Xamarin since Chrome had the same issue - crash when browse file / save file, other apps too. I am pretty sure it's a bug in the system level. – imgen Apr 07 '17 at 23:52
  • create crash dumps of Windows inbox tools (notepad.exe) if it has the same issue and share the dmp: http://msdn.microsoft.com/en-us/library/bb513638(VS.85).aspx. Set **DumpType** to 2 to get a full dmp – magicandre1981 Apr 08 '17 at 07:02
  • Yup, notepad.exe has the same issue – imgen Apr 10 '17 at 08:54
  • @magicandre1981 I collected the dump, what else? – imgen Apr 10 '17 at 09:04
  • zip the dmp, upload the zip to OneDrive, create a share link and post the share link here. I'll look at the dump and also ask my Microsoft contacts for help. – magicandre1981 Apr 10 '17 at 16:01
  • @magicandre1981, the link is https://1drv.ms/u/s!Au3MY0PcVMtTjt4XyF0ocQnpAa5q7w thanks – imgen Apr 12 '17 at 12:40
  • yesterday there was an update to 15063.138. do you see the crashes here, too? also generate a FULL dump, not a minidump. create a DWORD DumpType and set this to 2. – magicandre1981 Apr 12 '17 at 13:45
  • I did as told, this is the link of the dump file https://1drv.ms/u/s!Au3MY0PcVMtTjt4YyK0V5Qs1rG3OOQ – imgen Apr 13 '17 at 23:30
  • the dump shows a memory corruption for shell32.dll. use first chkdsk to look if your NTFS is damaged, next run [DISM](https://superuser.com/a/755684/174557) to look for damaged system files. Have you installed the last update to update to 15063.138? – magicandre1981 Apr 14 '17 at 07:11
  • do you also see the crash if you disable Bins ( C:\Program Files\1UPIndustries\Bins\v1.1.0.784\TaskbarDockAppIntegration64.dll)? – magicandre1981 Apr 14 '17 at 07:17
  • It cannot be with disk damage because I had this issue with both my machines. It could be Bins though. I'll see whether it is Bins that is causing this issue – imgen Apr 15 '17 at 04:01
  • Indeed it was Bins that is causing this issue. I'll uninstall it. Thanks for the help. – imgen Apr 15 '17 at 04:03

It turns out that it is the Bins program that's causing these crashes. Thanks for @magicandre1981's help!
