hello,
there is problem in your spreadsheet.
I would like to confirm that if your time values are correct.
You just need to replace the "." with ",". (Its german formatted excelsheet)
I just did the above changes and there is no error, model is able to simulate (just use the attached sheet) but my concern is with your time values which are to the power of 7.
Thanks

Is there any reason you are using Variable-step solver?
One way you can avoid this is by setting the Sample time in Spreadsheet block to small value (for e.g. 1e-8) as your time values are very small.
The Sample time parameter specifies the sample time that the From Spreadsheet block uses to read data from the spreadsheet.
-1 value inherits the value the from the block into which the From Spreadsheet block feeds data.
Just for your understanding try changing the sample time from 1e-5, 1e-7 and 1e-8 and see the corresponding plots.
I think most of your settings are auto. I would recommend you go through this page:
Choose a Solver: https://de.mathworks.com/help/simulink/ug/choose-a-solver.html
All the best!
