It is not a big problem.
This message means your system is blocking the aswSP.sys driver, part of Avast antivirus, because it’s flagged as unsafe.
First, update Avast—it might fix the issue.
If you trust the driver, go to Settings > Privacy & Security > Windows Security > Device Security > Core Isolation and turn off [Memory Integrity] temporarily.
If the issue keeps coming up, you might want to switch to another antivirus.
