dotnet tool list -g failed when run multiple times simultaneously

Prerequisites

1. net50 sdk and runtime are installed. May be another core sdks affect. Sorry, I don’t have a clear computer to make pure experiment.
2. Any dotnet tool is installed. I have an installed fluentmigrator. I installed it by next command:

dotnet tool install -g FluentMigrator.DotNet.Cli

Seems it doesn’t matter what dotnet tool is installed

What to do

Run multiple commands

dotnet tool list -g

It matters to do it simultaneously I wrote a small c# console, see attached zip file (described in Reproduction section below)

Expectation

No errors, just a table with installed tools in the output of each run command.

Reality

Some of run commands failed with invalid output like this:

Package Id                     Version      Commands Warning: tool package 'fluentmigrator.dotnet.cli' is invalid, contact tool author:
Failed to retrieve tool configuration: The process cannot access the file 'C:\Users\username\.dotnet\tools\.store\fluentmigrator.dotnet.cli\3.2.11\fl
uentmigrator.dotnet.cli\3.2.11\tools\netcoreapp2.1\any\DotnetToolSettings.xml' because it is being used by another process.

Reproduction

See attached zip file with c# console solution. DotnetToolListIssue.zip It runs 10 commands. At least 2 of them fail run by run stably On my computer an output of console looks like this:
