qtcreatror crashes after global search when going to the line in the source code wit a double click

Dear colleagues,

although I use qtcreator for many years, I came across this problem the first time. On the other ubuntu machine qtcreator works fine. The error happens on an Lenovo laptop and the main difference to the other machine is that it has an Nvidia graphics card and the cuda environment e.g. compiler etc  is installed for GPU programming. After having done a global search in qtcreator for a string in C++ source code and clicking on the line to open the file, I get in the window where I started qtcreator (version 6.0.2 based on Qt 5.15.3, which is installed) the following message:

Qt Concurrent has caught an exception thrown from a worker thread.
This is not supported, exceptions thrown in worker threads must be
caught before control returns to Qt Concurrent.
terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc

No issue found matching the above-mentioned error.

If you need any further info, please, do not hesitate to contact me.

Best regards

Bernhard
