Only crashes and error messages since the update to 7.0.6

[FrankKlein]

The update has been around for a while, though I've always put it off until now. And as it turns out, for a good reason: since the latest update, I only get error messages. I don't know what the new "update" is supposed to bring, except some improvements in the GUI.

PC was already restarted after the update, just as info.

So, the problem is that sometimes I can start a new VM and sometimes not. The VM is W10, if relevant. Everything has remained as it is so far, nothing was changed at all after the update. It's even worse when I want to boot/activate a saved state, that doesn't work at all by now since the update. There come then error messages like:

Callee RC:

RPC_S_SERVER_UNAVAILABLE/0x800706ba (0X800706BA)

or

The instruction at 0x... referenced memory at 0x0000000000. The memory could not be written. Click on OK to terminate the program. Click on CANCEL to debug the program.

Same here, it plays on a W11 guest and W10 Host. VBOX.log says: 00:00:27.027392 !!! rtR3WinUnhandledXcptFilter caught an exception on thread 0000000000001cec in 26520 !!!

This happens when taken the VM from a saved state back to a running VM. The only way to continue is to use the Discard option for this VM.

I hope there comes a fix soon, as it happened too often already.

Thanks
