after some seconds it is crashing silently (no IDA dump, nothing...)
Next time you open up the idb IDA is complaining about unexpected crash, eg:

Research direction

Start by reproducing the silent crash with the latest IDA77 release binaries on IDA 7.7 for Windows and the affected input binaries shown in the report. Investigate the crash without an input file, stack trace, or named source entry point; done means the reported binaries no longer cause IDA to terminate silently.
