Scala-cli run command incorrectly reports Fatal invariant violated.

[dasm0012]

Version(s)
Scala CLI version: 1.2.1
Scala version (default): 3.4.1
Scala 3.4.1, JVM (22)
WSL/Ubuntu

Describe the bug
When repeatedly executing scala-cli run command on a file that hasn't changed, scala-cli reports "Error: Fatal invariant violated: reportEndCompilation was called before processEndCompilation" - but still executes the scala file

To Reproduce
Create simple scala file (e.g. Hello World in main function)
Execute: scala-cli run ./hello.scala => works as expected
Execute again (no changes in hello.scala file): scala-cli run ./hello.scala => Fatal invariant is reported

Expected behaviour
No fatal invariant is reported

I reported the same to Metals, I guess it belongs here, or to Bloop maybe?

scalameta/metals#6266

This seems to be the same issue as scalameta/metals#6271
For now the workaround is to revert to using an older version of Bloop (1.5.12-sc-1)

scala-cli clean .
scala-cli --power bloop exit
scala-cli setup-ide . --bloop-version 1.5.12-sc-1

The issue itself is most definitely tied to Bloop and will be fixed upstream.

Shall we open an issue there? I don't see one related. Which Bloop version introduced the problem?

[Gedochao]

@spamegg1 No need to introduce an issue, I think, it can be tracked here.
@tgodzik is already working on it in scalacenter/bloop#2306
It will then need to be ported to our fork of Bloop at https://github.com/scala-cli/bloop-core
The version which introduced the problem is 1.5.16-sc-1.

Thank you for the very quick workaround + resolution :-)
