Paint.net fails to finish launching (newest version) (solved: SentinelOne AV as usual)

[Ah146]

I've tried two ways to start the program:

1) Click the program icon

2) Click to open a *.pdn file (which automatically launches the program)

 

In both instances, the program doesn't finish loading and the only way I can close it is via Task Manager.

All I see is the image I attached.

I've rebooted several times and even updated my Dell BIOS.

 

I do have a bunch of plug-ins (some are probably old), but everything was working fine until today.

 

Hope someone can help.

 

I apologize in advance if I haven't posted this correctly...

 

Thanks!

Please report this to Sentinel One (antivirus). Their software is completely breaking Paint.NET 5.1 and there's nothing I can do on my end to fix it.

Greatly appreciate the feedback.

I will send a complaint to Sentinel One!
