Help understanding some crash logs

[Eaarame]

I started having some crashes in Riften when attempting to load saves there. Can someone please help me make sense of them. I am posting two of them.

[rabitsrule]

try disabling spid sounds like that mod is the culprit and see if you get the crash

[rabitsrule]

or see if the mod has an update and see if skse is up to date and compatible with that version of the mod

[Altbert]

You are clearly using SSE 1.6.640, which requires SKSE64 2.2.3. Faster HDT-SMP seems to require SKSE64 2.2.2 (as shown in the crash log). The download site of Faster HDT-SMP is not really clear about which version you need to install, and I can't tell you either, as I have never used that mod.

[jonnin]

an unhandled exception is exactly that. Programming languages have a concept of 'exceptions' which are errors, and handlers for them, which are bits of code that get called when the exception happens. For example, you could make it an exception to divide by zero and handle that by giving a default result instead. If the programmer did not handle one of the exceptions that causes a program to crash (this is a 'soft' crash where the operating system / CPU / something halts execution to prevent damage to data or rarely, hardware) properly, the program crashes with this error. Mods can create these kinds of errors by introducing problems where none were found in the base program during testing.

An access violation is an attempt to read or write to memory that does not belong to the program. These were added for security reasons; so that viruses and malware cannot read memory belonging to other programs or modify a running program's code to make it do something else and so on. There are ways to force your program to do these things anyway, so it usually is caused by a program error, not actual malware ... malware doing it intentionally will pretend to be a system level program that is allowed to at least look at the other program's memory without triggering anything. /facepalm ...

if this is a mod, it is probably behind it: D:\a\Spell-Perk-Item-Distributor\Spell-Perk-Item-
but I know little of skyrim modding, and you should refer back up for possible fixes.

[Altbert]

Your version of Faster HDT-SMP is for another version of SKSE64, that's what line [10] is indicating.

SKSE64 2.2.2 is for Skyrim SE 1.5.97 not for 1.6.640. You probably downloaded and installed the wrong version of Faster HDT-SMP. I have no idea if SPID may be a culprit here also, but check if you have the correct version of SPID.

[Altbert]

Just checked: for SSE 1.6.640 you need SPID 6.6.1.

[Eaarame]

I rolled back to a different version of SPID and HDT-SMP and that fixed the issues
