"There was an issue starting the index server" message appears repeatedly.

[RCL]

Hi,

Vs-Chromium sometimes would refuse to start, stating
"There was an issue starting the index server. You may need to restart Visual Studio.
One or more errors occurred.
Error starting debugger thread.
Error creating process from file ".....long path to Extensions folder...\VsChromium.Host.exe": Access is denied".

Restarting Visual Studio does not help. This message can appear for a second Visual Studio instance while the first is still working fine. Once the message appeared, there's no way to go back - you need to reboot (possibly relogin would also help, but I didn't try).

VsChromium.errors is full of messages like

As for the log itself it has pretty much the same information as the window:
