I also noted on the "Search for test cases" selector in the TestComplete adapter installer was locked as "Execution Plan" and could not be changed.
I had exactly the same problem with the runs of my test from Azure Devops.
To solve it, you can try the fellowing actions:
1_Fom the task "VsTest- testassembly", clear the field "Test filter criteria"
2_Execute the pipeline => TestExceute runs the test without the error message
3_Write your filter one more time in "Test filter criteria" (in my case, I tried another filter criteria like "Name~MyTestName" just before and runned one more the pipeline=> everything was fine)
4_Run your pipeline=> Everything should be OK. No error message about "a file name has not been provided".
Hope this procedure solved your problem as it solved mine.

In my case i dont have a filter criteria 😞
