Hello,
Please be advised i am also getting multiple applications with KERNELBASE.dll crashes. including Microsoft SQL Server Management Studio 20.2.1, i cannot even uninstall the application as KERNELBASE.dll crashes the installer/uninstaller.
This issue started middle of April and on April 30th performed a complete Windows 11 system wipe, reinstall with cloud download for install. Within 24 hours, the issue re-appeared on multiple applications.
Every crash references the DLL and .Net Framework Version: v4.0.30319
Microsoft has introduced this bug somewhere and its causing a lot of problems.
