Bug Report Elgato HD PRO Crashing often upon Activation + Encoding issues

I stream with an Elgato HD PRO internal capture card, and OBS really does not want to play nice with it.
I have updated its firmware and software. By itself the program runs fine. Once OBS is thrown into the mix, things become chaotic.

Log of Streaming + Recording attempt resulting in crash:

Crashlog:

Title says it all really. This has been happening with OBS Studio consistently. Sometimes it works great, but more often than not the program crashes upon hitting Activate. When Activate does not result in a crash, it is sometimes possible that there is a strange delay between the gameplay and preview when there should not be any, and flipping activate on and off removes it to practically zero. Again, doing that step is risky, because it can also result in a crash. This only happens when viewing the Elgato through OBS.
Sometimes this causes OBS and Elgato to be stuck in my Task Manager and I have to end their processes from there. Occasionally OBS will refuse to be terminated and will give me "Access Denied" and will take up to ten minutes to remove itself.

With my rig being quite good for streaming, this makes no sense I feel like something is wrong with how OBS communicates with the Elgato drivers. This does not occur with my Avermedia capture card. I use Elgato capture cards because they are more fit to interpret analog signals given by some of my older consoles.

I have completely wiped + reinstalled drivers and programs several times to the point I am convinced this is not a fix for this specific issue.

A side issue unrelated to this one possibly: I could also mention my stream has been having Encoder Overloaded issues since the current update 0.17, resulting in massive dropped frames. I assumed it was my system being overloaded somehow, but no amount of reducing encoding settings seems to resolve the issue. Nothing appears in the logs that jumps out to me beyond the acknowledgement that frames are being dropped due to encoder lag. Possible memory leak? Usually these stutters occur after a few hours of streaming, but this was not the case prior to this update and I could stream at higher more intense settings than in those logs for 8 hours on end - no issues at all.

If anyone sees anything in these logs, or requires more information, please let me know. I'd really like to figure this out.

I can probably not help you much with your issues, but I can say that obs studio feels much more instable to me than the original. I'm also using an elgato hd60 pro and my obs studio crashes ALOT when starting/exiting the program. thankfully it doesn't do it while streaming unless I switch the HDMI out to stream pc games while using the NVEnc encoder. This crash will be pretty bad because as you mentioned above I cannot kill the process in task manager, so I either have to wait around 10 minutes for the program to close or restart my pc.

I don't even know if any of these issues are related to the capture card. The hd60 pro capture is also very delayed for me in obs studio but I never felt like it's an issue because I use a seperate monitor to play my games on. I can also confirm that this delay was not there when I used an avermedia extremecap u3 to capture. Also realized that the delay on the obs preview screen (with the hd60 pro) gets worse over time, so there might be something weird going on with obs.

Hi,

The crashing does indeed involve the HD60 Pro drivers.

Please re-install them by following this guide - http://e.lga.to/uninstallwin and let me know if that helps or does not.

Unfortunately this did not fix the issue. I have uninstalled everything following all directions and reinstalled the latest driver. I restarted my computer with each prompt given in the instructions and when Elgato software asked me to.
Upon entering OBS, tested the card.
Turned the card on (1st time went well).
Turned the card off.
Turned the card on again (2nd time went well).
Turned the card off.
Turned card on again. Crash.
OBS is now stuck in my task manager doing exactly what MDZ jimmy and I have described.
Here are the Crash logs.

This one happened immediately.

In fact now they just keep happening. Over and over way more than before.

reinstalling the drivers seems to have worked for me. I opened/closed obs multiple times now and it doesn't seem to crash now. my obs crashing issue when switching hdmi out seems to only be related to NVEnc, so thanks for the support LtRoyalShrimp :)
