Windows Smart App Control blocked UserContributedStudies_64.dll — Event Viewer shows Event ID 3077, CodeIntegrity: 'did not meet the Enterprise signing level requirements.' Wanted to flag in case your signing certificate needs renewal/upgrading.

I'm rather sure I do not use any but they exist for perusing and vetting. So, what should I do.

I'm running Windows 11 Pro.
Noteworthy: I've been using SC for months now without seeing this issue. I recently renewed by AV, Bit Defender but changed product from Ultimate Security to Family Total security.

My Rig
Device name  MSI
Processor  AMD Ryzen 9 9955HX3D 16-Core Processor (2.50 GHz)
Installed RAM  96.0 GB (93.6 GB usable)
Graphics card  NVIDIA GeForce RTX 5080 Laptop GPU (16 GB)
AMD Radeon(TM) Graphics (2 GB)
System type  64-bit operating system, x64-based processor
Pen and touch  Pen support

This seems to be a code integrity is MS is flagging as 'not meeting their requirements' for safety.

Please advise.

Thank you.
Kind regards,
Gary Francis Mohamad
