Error running validation checks on all chains

[vdamle]

Bug Description

Occasionally, the test to run validation checks on all chains - just validate "*" fails many checks. Upon looking at the error logs in CI, there appears to be a concurrent map read and map write occurring which causes this error. See CI Job output

Steps to Reproduce

run just validate "*"

Expected behavior

Validation should pass without errors/crashes.
