(Emergency Help Required) License Error

[koreanistud]

Hello, I am a high school student learning animation in Korea. The program suddenly turned off while working on a team project last Friday, and when I ran it again, I got a license error message and couldn't write the program. The program is not available even though the license is actived. At first, I thought it was because of the Windows update, but a few days after the Windows update, an error occurred. Trying to fix the program but not changing and team work is being delayed
Yes, help me. Help me!

Computer: MSI Sword 17 A11UD
Windows Update Status: Latest
