Lasers went berserk after update

I have a Longer B-1 40W and an Algolaser Alpha 22W. I use LB on a Dell desktop running Windows 10 or a little junky Lenovo laptop, also running Windows 10. Both lasers worked great prior to the latest update. Now they don’t home at left front- they go to rear right, they lose their place when cutting a file, they bounce against the rails and limit switches like crazy and air assist stopped working (even though the tab is clicked on). I contacted Longer and they sent me what should be the proper commands, but the Longer still loses its place and doesn’t cut properly. If I frame something prior to a cut, it will frame, but then cuts in a totally different area. It has to be something with the software, because both of my lasers are being weird. I uninstalled and reinstalled Lightburn, erased the preferences folder, tried an older version, reset commands to default. Nothing has helped. I don’t know enough about lasers to figure out what I’m doing wrong. Please help. Thank you.

Do you have an offset set?

Windows is known for not reading some files when you run updates, try loading a preference file from a day or two before you updated Lightburn.

Unfortunately, I permanently deleted them. I wiped every trace of Lightburn software off my computer, including the registry and any hidden files, using a specialized app. After 2 days of trying everything I could think of, I think the Algolaser is working properly. I am now using Lightburn 1.6.00. The Longer is still malfunctioning, it homes and attempts to frame, but not accurately, then loses its location and starts cutting in a totally different place. And sometimes it stops and makes awful grinding noises.
Maybe you are on to something, Defender showed a pop up window saying it wanted to disable some of Lightburn’s features which I bypassed. It thinks it’s malware.
It’s just so frustrating because it was working perfectly prior to the update.
