In VS2015 with 1.50.12752 and Symfony 5.2 I get crashes

Bart

When I create a new Symfony 5.2 project and take its composer.json, VS2015 opens a project correctly the first time, i.e. it installs all the missing var, vendor etc files. When I then re-open the same project, VS2015 displays the info below in its composer output. This does not happen with a Symfony 5.1 composer.json.
System.AggregateException: One or more errors occurred. ---> System.NullReferenceException: Object reference not set to an instance of an object.

I have a small test zip file that I could email to someone.

Update: I can now also make this happen with a Symfony 5.1 composer.json. If the project was installed (var, vendor etc) with an older DevSense version, it keeps working until you delete everything except the composer.json. A new install will show the crash the second time you open the project, i.e. once the first open has installed everything.

Thank you @Bart - this is great feedback. We've everything we need to fix this within the next update
Bart

This seems fixed in 1.50.12791
