APC Index Mismatch when opening Outlook attachment after update Windows 10 1903
« on: June 20, 2019, 09:08:41 AM »
Hi to everybody,
after upgrading my Windows 10 to version 1903 (build 18362.175) I get a blue screen each time I try to open some kind of attachments in Outlook 2016 (version 1905 buld 11629.20246) for example PDF files or double-clicking on links in the email body.

The error message is APC_INDEX_MISMATCH without any sub-code or specific file name or other information

If I temporary turn off the Avast protection I can open the same attachments or links without any problem.
Avast is updated to version 19.5.2378 (build 19.5.4444.505)

What can I do?
Thanks in advance

Update your virus definitions and reboot your computer.
