Hi,
Thank you for posting.
If everything worked before, a quick solution is to restore the system back to the previous status when the issue didn’t occur with System Restore. (Note: Performing a system restore may cause the loss of the current system settings; therefore, before doing this, please make sure that the system restore point is not too old and set a restore point for the current status.)
Based on my research, this error message should be related to an application error of Adobe Flash. At this time, please try the following to narrow down the issue:
1. Please check if the issue will occur in Clean Boot environment:

2. Try Compatibility mode
Make older programs run in this version of Windows

3. Repair or reinstall Adobe Flash to see if it will work again.
Considering the issue is related to a specific software, it is recommended that you contact Adobe for technical support as they are familiar with their products.
