goroutine fatal error: concurrent map writes

[putarpuar]

Describe the bug

I have added TERRAGRUNT_PROVIDER_CACHE=1 infront of the terragrunt run-all plan command. But sometimes I get "fatal error: concurrent map writes". I attached the complete log to this report.
I configured this in my .terraformrc file, not sure if this is relevant:

plugin_cache_dir = "/home/vscode/.terraform.d/plugin-cache"
plugin_cache_may_break_dependency_lock_file = true

And some envs.

TERRAGRUNT_DOWNLOAD=/tmp/terragrunt-cache
TERRAGRUNT_PARALLELISM=20
TERRAGRUNT_USE_PARTIAL_PARSE_CONFIG_CACHE=true
TF_INPUT=false
TF_PLUGIN_CACHE_PATH=~/.terraform.d/plugin-cache

Steps To Reproduce

I can't reproduce it. I happens around every second time I run the plan over around 30 modules.

Expected behavior

A understandable error, if I did something wrong :)
