I played music from my internal SSD that is my music library with Media Center 31 a few days ago using my Air Pods Pro 3. It was the first time using Media Center since updating to Windows 11. I had no issues; MC 31 ran for a couple hours. This afternoon, I am having a major technical episode. The app starts fine. As few as 30 seconds open, it quits suddenly, but no error report appears. I first noticed erratic scrolling motion when browsing music lists. The one I was scrolling was displaying Thumbnail view. My mouse pointer jumps around randomly. Then MC shuts off instantly. This behavior is puzzling.

I restarted once already; I thought it was a computer performance issue. Then I looked at the hardware and connections. I saw the mouse cable was connected but loose. That didn't fix anything. I will refresh MC 31.0.87 next and restart the computer in my next attempt in an hour or so.

Happy New Year everyone!

Antivirus

[Maeghaus]

Hello, Jim. I have Malwarebytes Premium. Malwarebytes is a solid program, but it has a habit of false positive scanning results. It would be the first time for MC to run into a conflict with an antivirus program. I'm running Windows 11 which has quirks of its own.

Uninstall it to test.

I removed Malwarebytes completely and restarted the system. But MC 31 continued to simply vanish about 30 seconds after opening. I don't know much about configuring the present version of Windows Defender but can investigate settings and make some changes there. I should look for an online guide. The JRiver logs might indicate something. And I can make a video capture of the screen to submit. Currently, I don't know why MC 31 disappears off the desktop.

Try turning off auto-import and see if the crashing stops. If it does, you likely have bad file(s) which are causing MC to crash when auto-import runs in the background. If that's the case you'd need to enable logging in MC, reproduce the crash then look at the bottom of the log files to see what the last file(s) MC was trying to import was, then try moving them to a different directory that MC doesn't import from then try again.

Thanks for the additional posts. The point of anti-virus/malware/ransomware programs is to recognize external and embedded threats. More often, though, I get scan reports occasionally where everything in my computer is flagged (excepting Windows itself). Not as viruses or ransomware but as Potentially Unwanted Programs (PUPS). A few vendor files and programs get flagged as Malware. I examined some of my scan logs; this behavior is overtaking the task of seeing real threats. It doesn't make a logical case for using anti-virus software.

I will pick up on reporting in the morning. -- Tom

After uninstalling Malwarebytes, try re-installing MC.

We've seen antivirus programs modify JRiver files before.

Setting up a test library might tell you if a file is bad.

Thanks Jim, I'll work on your suggestions next. I am submitting a log file I made this evening. I have a window capture video of MC idling, then quitting if you need to see the behavior I'm describing. -- Tom

I removed Malwarebytes and Media Center 31 completely late last night. I got around to installing Media Center 31.0.87 this afternoon but did not install Malwarebytes. MC is working now, no issues.

It took me along time to become aware that every report I got from a Scan showed the same items. It flags two programs as malware, and an additional 40 paths that are "PUPs" (Potentially Unwanted Programs). I've waved it off as a quirk but I realize now that MB is the main cause for a lot of things just by being installed. I got instruction errors after the PC had been on a while, crashing Explorer and the machine had to be Reset. I think Malwarebytes was the culprit all this time. I stopped using it. Windows Defender seems adequate for my needs.

Thanks for reporting the solution.

That's odd behaviour. I use Malwarebytes and MC on Windows 11 with no issues.

It may be OK if you've configured it, but take a look here:
