Problems installing ReSharper: JetBrains Installer.ReSharper.Bootstrap could not run Follow

I have problems installing ReSharper. Every time I start the installer, the following error occurs: "JetBrains Installer.ReSharper.Bootstrap could not run.

Could not Ioad the JetLauncher Managed Core into the

application domain. Could not Ioad the assembly from

resource #777. The File or Assembly "208936 bytes Ioaded

from mscorlib, Version-4.0.0.0, Culture-neutral,

PublicKeyToken=b77a5c561934e089" or a dependency

could not be found. Exception from HRESULT:

OxD0000003"

I am using VS 2022. My System and VS is up to date.

Things i have already tried are:

• updating Anything

• Windows

• VS 2022

• .NET CORE (version 6.0.401)

• different Installation Methodes

• web Installer

• offline Installer

Has anyone the same problem or can someone help me? Thank you
