Panic: runtime error: invalid memory address or nil pointer dereference

Introduction

When I use tflint to check all terraform files in the current directory，I run the following command:
find . -type d | xargs -I {} tflint {} --color

tflint is working well, but I get part of outputs like this：

Panic: runtime error: invalid memory address or nil pointer dereference
-> 0: main.main.func1: /main.go(21)
-> 1: runtime.gopanic: /panic.go(884)
-> 2: runtime.panicmem: /panic.go(260)
-> 3: runtime.sigpanic: /signal_unix.go(835)
-> 4: github.com/terraform-linters/tflint/terraform.(*Parser).LoadConfigDir: /parser.go(71)
-> 5: github.com/terraform-linters/tflint/tflint.(*Loader).LoadConfig: /loader.go(65)
-> 6: github.com/terraform-linters/tflint/cmd.(*CLI).setupRunners: /inspect.go(117)
-> 7: github.com/terraform-linters/tflint/cmd.(*CLI).inspect: /inspect.go(41)
-> 8: github.com/terraform-linters/tflint/cmd.(*CLI).Run: /cli.go(98)
-> 9: main.main: /main.go(34)
-> 10: runtime.main: /proc.go(250)
-> 11: runtime.goexit: /asm_amd64.s(1594)

TFLint crashed... :(
Please attach an output log, describe the situation and version that occurred and post an issue to https://github.com/terraform-linters/tflint/issues

I want to know why and how to resolve this.

Thank you for your report. This seems to be a panic that occurs in limited circumstances. Fixed by #1598.

Although it is the cause, I think that there is a file that exists but cannot be read.

I'm also facing this issue #1646 with 0.44.1
