Here's what's going on:

• When installing sunpy locally from a fork, the reported version will be wrong if the Git "tags" from the main repository have not been downloaded. Typically, the tags will be downloaded when the main repository is added as a Git "remote" (i.e., as upstream) and fetched.
• If the reported version is sufficiently wrong, two of the asdf-related unit tests will fail because a warning is emitted in a validation check.
• The unpacked data in these asdf-related unit tests include an array that is memory mapped from a file, and this file is closed before the unit test ends.
• As part of the pytest failure output, pytest tries to print out the unpacked data, including the memory-mapped array, which means that it tries to read from a closed file, hence the access violation or segmentation fault.

The docs addition in #7407 should make it less likely for new users to be in this situation
