Describe the bug
A clear and concise description of what the bug is.
During startup the client crashes but does not generate a crash report because laggoggles issues an internal shutdown order to the client.

To Reproduce
Steps to reproduce the behavior
Add Lag Goggle version 4.8 to an instance of StoneBlock 2 version 1.15.0 as found on the Twitch launcher. https://www.curseforge.com/minecraft/modpacks/ftb-presents-stoneblock-2

This error affects both FAT and THIN versions in the client environment. In the server environment there is no issues.

If you are using SpongeForge, which version are you using?
N/A

Please provide the early startup messages starting with [LagGoggles-Boot]

If you used the word 'error' somewhere, always provide the stack trace along with both debug.log and latest.log
Twtich does not create a debug.log file, therefore no debug.log file can be supplied. Attached is the latest.log file.

Thank you for this update. In addition I have tagged onto a recent bug report that another user opened with p455w0rd's library about this issue. It would seem that he has updated the mod to version 156, however I am unable to verify if it did in fact resolve the issue since he failed to also update his other mods to be compatible with this newer version.

p455w0rd/p455w0rds-Library#45

So at this point, even if he has resolved the issue in 156, because his other mods cannot run because of a dependency issue, his fix at this junction in time is moot. Hopefully we see this resolved quickly.

I hope so too! Thank you for reaching out to the developer. Now we know it's being worked on 👍

It's literally only /dank/null. Way to lie and overexaggerate Gunner, cuz that always helps. Remove /dank/null and shit works.

Thank you for looking into this, @p455w0rd

This part is of interest:

This happens when p455w0rdlib is installed. I did a deep-dive into this issue in #71.

I have sent a request to address it here: p455w0rd/p455w0rds-Library#26 (comment)

Sadly, this isn't an issue I am able to fix, since it's not LagGoggles.

LagGoggles just makes sure its mixins have been applied and make sure you don't waste your time with a broken installation.
