Understanding docker container run invalid reference format

I built a Dokerfile, created an image, and ran a docker run.
The following error cannot be resolved:

 docker: invalid reference format.
See'docker run --help'.

When I looked into it, I looked at the article that caused the copy source and destination path to be written after -v
I tried the following pattern, but all of the above error messages appear.
If you know how to solve this problem, please let me know.

Win10 Pro
Powershell
Docker version 20.10.17, build 100c701

C:/PC-Work/dockerevenv

docker container run-it -- name sample-python-v${PWD}/ex01:/tmp/mydir/sample/python:latest

docker container run-it --name sample-python-v C:\PC-Work\dockereenv\ex01:/tmp/mydir/sample/python:latest

docker container run-it -- name sample-python-v "${PWD}/ex01/:/tmp/mydir"/sample/python:latest

docker container run-it -- name sample-python-v "C:\PC-Work\dockereenv\ex01:/tmp/mydir"/sample/python:latest

windows docker powershell

Docker for Windows × volume option × path specification, depending on what is verified in , the string given to -v is

-v "C:\test":/test
-v "C:/test":/test
-vC:/test:/test

All of them will be successful.(I haven't tried it yet, so I don't know if this result is correct.)

However, this is the result of the verification at the command prompt (cmd.exe), and PowerShell shows a different behavior.for Shell generally interprets and makes changes to the arguments.You can see them by typing cmd/cecho followed by to see how they are interpreted

.command prompt (cmd.exe)
C>cmd/cecho-v "C:\test":/test
-v "C:\test": /test
C>cmd/cecho-v "C:/test":/test
-v "C:/test": /test
C>cmd/cecho-v C:/test:/test
- vC: /test: /test
→In the range we tried here, the input string will be passed directly to the program.
PowerShell
PS>cmd/cecho-v "C:\test":/test
- vC:\test:/test
PS>cmd/cecho-v "C:/test":/test
- vC: /test: /test
PS>cmd/cecho-vC:/test:/test
- vC: /test: /test
→" will be deleted and a blank space will be inserted.
To be interpreted and not rewritten by PowerShell, a PowerShell specification escape is required and the input is as follows:
PS>cmd/cecho-v`"C:\test`":/test
-v "C:\test": /test
→ Escape " with backquote.
PS>cmd/cecho-v`"C:/test":/test`
-v "C:/test": /test
→ Tie the string containing " with a single quote '.
Based on the above, would the following be an example of typing on a PowerShell?
docker container run-it --name sample-python-v`"C:\PC-Work\dockereenv\ex01`":/tmp/mydir/sample/python:latest
→Escape with a back quote while tying it with ".The path delimiter can be /\.
docker container run-it -- name sample-python-v' "C:\PC-Work\dockereenv\ex01": /tmp/mydir'/sample/python:latest
→ Escape the string with ' while tying it with ".The path delimiter can be /\.
docker container run-it -- name sample-python-v C:/PC-Work/dockereenv/ex01:/tmp/mydir/sample/python:latest
→ Use / as the path delimiter and do not quote.
