This is a known issue of coverlet (vstest to be exact) listed here: https://github.com/coverlet-coverage/coverlet/blob/master/Documentation/KnownIssues.md#vstest-stops-process-execution-early
Potential workaround is to use the environment variable that increase the timeout time (see microsoft/vstest#3466) by setting VSTEST_TESTHOST_SHUTDOWN_TIMEOUT.
