Did you ever resolve this problem? I having the exact same one now, same error messages and every thing.

I've already re-installed and clean booted on both computers using the Purge script. Still just crashes with netdll problem the moment I move my mouse from primary to secondary.

Same problem as far as I can tell. I didn't upgrade windows versions but windows did apply a regular update somewhat recently I think. Everything was working fine for the last several months. It started breaking the last day or two with seemingly the same symptoms as OP. Crashes whenever I move my mouse to another monitor/connected PC.

Well something changed and it was (clearly) not MP nor have we seen anyone but you few reporting it.  Did ANYTHING change that you can think of on the settings \ software side?  Did any hardware change (mouse, network, etc)?

Did either of you try the clean boot (on both PCs) mentioned:

For what it's worth I was unable to fix the problem. I just quit using the software because I don't have the time to apparently wipe both my computers and reformat them like another in this thread did to solve it.

One would think the application might keep a rolling log somewhere with better information you could dig into. One that's not just the windows event log viewer. Or some sort of debug mode with resilient runtime exception handling so problems can be found and logged instead of just fast-crashing. But I guess not.

Let me know if you find something that fixes it for you.

I'm having this same issue. Happens at random times, sometimes when gaming, sometimes when vmware workstation is running, and sometimes when Firefox is running. Bascially, it's random. I've formatted and reinstalled on both machines and still persists. This is happening on my main computer, and restarting the service does fix it. I'm on Windows 11. Having some better logging inside the app would help.

So I'm getting this error message when Multiplicity crashes

As I suspected.

It's extremely unlikely to be Anti-Cheat. I've used it while playing games that have EAC, Denuvo, and many other Anti-Cheats and it has never once caused an issue over the course of multiple years. I am not saying it can't be a recent development, I just think it's very unlikely.

Mine also just crashes outside of game when I move my mouse from the primary to a secondary shortly after restarting the computer with next to no background apps running.

Yeah, I've checked what you have posted up there, was already on, still getting that error message. I even turned on "Run as Administrator" in compatibility mode, hoping it was an issue maybe with permissions and where the dmp file is located.

I have been able to get it to crash pretty consistently, if I move the cursor back and forth between the 2 machines quickly. Will usually crash within 15-20 seconds. Was doing this to try and get the debugger to work. Normally it will just crash within and hour or 2 of normal use. The other thing I wanted to mention is it only crashes on the primary machine. Secondary is always fine. My "fix" for now is just a powershell script that restarts the multiplicity service, but that's kind of a bad workaround.

My crashing seems to be an issue with Windows 11 with updates from the last year. I pulled out 2 computers that haven't been updated in year and some change. Tried to get them to crash and couldn't. Used a stepper motor to move the mouse back and forth for 24 hours solid. No Crash. Did all the windows updates, and now it crashes about as consistently as my 2 machines I use every day.

I am receiving the same error on Windows 11 PCs. Mine seems to be related to syncing clipboards. If I copy an image to clipboard from remote and move to master - and move back and forth between the two - it reproduces. It did the same thing with files. I think sometimes I move to fast and flip back and forth before things are able to sync. I am also getting:

But this is set:
