It’s happened several times, at first I had no suspicion on Unreal 5 because it was downloaded directly from Unreal website.
1st install, unreal 5.42 works fine, but an existing CorelDraw 2019 stop working, the application start normally but when I was trying to create a New File or try to open an existing file the Application froze, I don’t know the cause so I reinstall all things from the scratch, I formatted the C drive then Install new Windows 11, a fresh installation. but after I Installed Unreal 5.42 CorelDraw2019 can’t works anymore.
Reinstall a new system again, then work with CorelDraw2019 for a week smoothly without problem, then I tried to Install Unreal 5.42, then CorelDraw 2019 stop working.
I use BITDEFENDER free antivirus.
Win 11 Home (10.0 build 22631)
