When remote performance test list is executed, first the whole project is downloaded from Storage DB, then first test is executed and it creates a temp folder to write the .tsperf results, so first test runs, saves temp .tsperf result from the run in this temp folder, sends the result to Storage DB and deletes the folder. Then second test starts its run, but it does not create the temp folder for the .tsperf results and tries to use the one created from the first test, which is no longer present - then crashes internally and execution is stuck.

Here is the example log
