Resharper Intellisense Not Working R#2019.1.1 VS2019

Completed

The Resharper intellisense in Visual Studio 2019 just stopped working today. No updates applied to Resharper, Visual Studio or Windows. This was working last week. If I switch from Resharper Intellisense to VS Intellisense, it works. When I switch back, it doesn't. 

 

I am seeing the following error logged when setting the log output for Resharper:

Hello!

 

Could you please specify if ReSharper stopped working in some specific solution only? If so please try suggestion from the following help article.

What about other ReSharper features: refactorings, navigation etc, do they work?

Thank you.

It does appear to be having the issue with only one solution and only in VS2019. I opened the solution in VS2017 and Resharper Intellisense is working. Other features (refactoring, navigation, etc) work.

I had tried that article before and followed both the Clear Cache button and manual clearing options but to no avail. There is no .suo file for this solution.

Thank you for the reply.

 

Could you please also try removing %LocalAppData%\JetBrains\Transient folder.

If that doesn't help please provide full ReSharper log, you can do it privately via 'Submit a request' form.

Thank you.

Deleting the %LocalAppData%\JetBrains\Transient folder worked! Thanks!

Unfortunately, it looks like the problem came back today. I have submitted a support request with the log attached.
