You also need to set DENO_UNSTABLE_TSGO=1

[amyssnippet]

amol@Amols-MacBook-Air deno-compat %DENO_UNSTABLE_TSGO=1 deno check tests/ignore_test.ts 
amol@Amols-MacBook-Air deno-compat %deno --version                                       
deno 2.6.6 (stable, release, x86_64-unknown-linux-gnu)
v8 14.2.231.17-rusty
typescript 5.9.2
amol@Amols-MacBook-Air deno-compat %

still didnt got the error!

[sigmaSd]

It seems you run into caching , because deno check didn't run at all , to run it should say in the first line Check file path

To provoke it to run just edit the file or run deno clean

[amyssnippet]

you are right

amol@Amols-MacBook-Air deno-compat %DENO_UNSTABLE_TSGO=1 deno check clean tests/ignore_test.ts 
Check clean
Check tests/ignore_test.ts
fatal error: concurrent map read and map write
