Media Player Classic: SBIE2101 OpenProcess (C0000022) access=001FFFFF initialized=1

Greetings! Since the latest Windows 10 update I've been having this annoying issue with MPC-HC. Sometimes, seemingly at random when I click the MPC-HC window, I get two messages:

Latest Windows 10
Latest beta
Also running:

Hello BatmanCatman,

Does the issue happen if your Antivirus protection is removed?
Does it work fine outside Sandboxie?
What are the exact repro steps that you follow?

I tried to repro the issue (minus MWB) but so far, nothing.

Regarding the memory message:

I disabled Anti-Ransomware and it still happens.

I'll try to figure out how to reproduce it, the only tip I can give now is to watch a lot of different videos in a row. I don't have them queued or anything but it's clearly more likely to happen the more videos I've watched in a row. I'll try to get Access Monitor to capture the next time it happens for you.

It seems to only happen when I'm running Chrome at the same time.

Hello BatmanCatman,

Still cannot repro. I have Media Player Classic playing a video loop + Chrome running in the same Sandbox...so far, so good.

As for your logs, there is a lot going on there, but I did notice something that did not come up on mine:
\Sessions\1\BaseNamedObjects\MediaPlayerClassicW

Try opening that path. Right-click on your Sandbox --> Sandbox Settings--> Resource Access--> IPC Access---> Direct Access
Paste:
*\BaseNamedObjects*\MediaPlayerClassicW
Hit Apply and Okay your way out.
Configure --> Reload Configuration
Re-try (if not difference, please remove this configuration).

If you can provide more info regarding the MPC version that you are using and type of video (avi, mp4, etc), I'll keep testing.
Also do try fully removing your security software (disabling it sometimes doesn't make a difference) to rule out any compatibility issues.

Regards,
Barb.-
