[BUG] RC QM Crashing PC

[NickoliVolkolf]

Describe the bug
Black screen freezing PC entirely within 5 minutes of starting quickminer.

To Reproduce
Turn on mining using 0.4.6.x

Expected behavior
For QM to not crash my PC. It just started with the RC from yesterday .6.0. Also tested using .6.5, same issue.

Version affected (please complete the following information):

• RC .0.4.6.0
• RC .0.4.6.5

Hardware
EVGA 3080 FTW3 Ultra, direct to PCI 3.0

Logs
Attached, I don't see anything really.
log.txt

Additional context
I downgraded to the latest Stable and it is running fine. You'll see that in the logs as well.

According to provided log, I would say you had issues with Excavator getting blocked by AV.

Also, can you provide all logs (including excavator logs).

[NickoliVolkolf]

Attached are the logs. I haven't changed anything AV wise, the whole folder is excluded as it has been from day 1 using QM. I've been mining on the latest stable since I opened this without any changes to the AV.

That is the problem; making exclusion is not enough, you need to "allow on device". Then it stops getting targeted by Defender.

[nicehashdev]

What is common for both logs you submitted is that speed goes to 0 before whatever happens. I am 99% sure it is Defender blocking Excavator. Make sure you allow it. Here is procedure how to do it: #204

[NickoliVolkolf]

I have defender off, including the firewall. Was something changed in the latest RC that would be causing it. I haven't touched anything since I started using QM in v0.3.0.6_RC (besides updating when prompted)

[nicehashdev]

I will repeat again; it does not help to have defender off or to have exclusion list. It would still block it unless you make "allow on device" exception for exactly that excavator.exe. It is a (intentional) bug by Microsoft to make mining very hard on PC.

[NickoliVolkolf]

You're missing the point of the bug ticket. It was fine for 2 months, now in the RC it isn't working. A generic defender causing it doesn't explain it. Unless there is a new excavator.exe packaged with the latest RC. If you want to close it with that, its up to you. I'll just stick to the stable version as I have no issues with it. And If you have defender off, there isn't a way to make an exception to a software that isn't running in the first place.

[nicehashdev]

Yes, there is new excavator.exe packed with it. In every new version, there is most likely new excavator.exe packed in because changes and updates are needed there too.

[NickoliVolkolf]

I'll upgrade to the latest RC again tonight and post the logs (with reputation based turned off). There isn't a way to exclude in defender as it isn't on. I don't see how excavator crashing/being blocked causes a PC to hard lock and need rebooted. But either way Thank you for your time. I'll post logs later.

[nicehashdev]

There is new RC version which is built using latest CUDA version (11.2 update2) which shall hopefully resolve all the unexplained errors. Try it please and report back.

[NickoliVolkolf]

So far so good. Been mining for about 20 minutes with no issues. I'll close this in an hour or so if everything continues to be fine. Thanks!

[nicehashdev]

Okay good. Glad your problem is fixed.

[NickoliVolkolf]

Yep still good. Thanks again!
