Stoned how do I exclude it exactly?

I've been having this problem for about a week now and the only thing fixing it is a computer restart, making me restart my computer several times every day. Even reinstalling Byond doesn't help (without restarting computer).
I have Avast but Byond folder is in its exceptions. I should not have any other active antivirus software.

The crashes happen when I sometimes open or use popup windows in SS13 (use machines which open a new window). Sometimes it also happens when the round ends and new one is starting.

I've tried reverting back to 1315 and even to 508 but it crashed with those as well. The first crash happened shortly after first installing 1316 though. Now I'm back using 1316.

I tried getting info with Windows debugger but it's giving me an error after attaching it to the crashed dreamseeker and listing some dlls.

(105c.1b2c): Break instruction exception - code 80000003 (first chance)
*** ERROR: Symbol file could not be found. Defaulted to export symbols for C:\Windows\SYSTEM32\ntdll.dll -
ntdll!DbgBreakPoint:
00000000`7773cc90 cc int 3

Also the Windows even viewer isn't giving much information.

EDIT:
I tried setting the symbol path with Windows debugger and the error went away but it's still not giving me anything related to dreamseeker.exe, byondcore.dll or byondwin.dll. Writing ~0s is giving me info about ntdll. The original list after attaching starts with:

I should have every possible exception on for the entire Byond folder and it keeps happening. Turning entire Avast off after it has once crashed doesn't help at all and I have to restart the computer.
I haven't tested what would happen if I disabled Avast every time I play but that would leave me without antivirus a lot.

OKAY, I think I fixed my problem.

This is exactly what I did.
I uninstalled everything doing with byond and dreamseeker, restarted my computer, reinstalled byond THEN moved the byond folder from program files(x86) to the normal program files.

I set the byond folder to be an exception as well in avast, even though that didn't work last time.

But after doing all these things together it seemed to work now.
