Code analysis corruption since 2023.3

We encounter strange code analysis errors. As far as I can tell, they occur on edited code. It seems, that the code analysis gets out of sync with the actual code.

The problems happen both in java and typescript tsx files.

Tsx file warnings

1.  It says eve is not in use: clearly it is used 5 lines later
2. It says sp is not in use: it is accessed the very next line

Java file warnings

Prior to the screenshot, to trigger the problems, I had inserted in line 5 the assignment s = null;

This leads to the correct warnings and indications: 

• lines before statement: sth like “variable is reassigned”
• lines after statement: sth like “s is always null”

When fixing the code by removing the assigment s = null; the warnings and indications remain.

Invalidating the cache and restarting the IDE does not help, maybe for very short time. But as soon as one begins to edit, the analysis lag(?) starts again. This makes the work with the IDE very exhausting and cumbersome.
