i have tried to launch 1.20.1 in windows 11 please repair it, i want my minecraft back

Send out the java executable file (only .exe) used when this error is triggered. I think there may be a problem with this method of obtaining java information 将触发这个错误时使用的java的可执行文件（仅.exe）发送出来，我认为可能是这个获取java信息的方法有问题

i'm using java 8 (idk why 32-bit) 8.0.3810.9 - the latest version this happened AND after a clean install of fluent launcher, and i hate it needs to be complicated i rechose the javaw.exe file in the settings tab>java runtime, but still not working...

C:\Program Files (x86)\Java\jre-1.8\bin\javaw.exe the directory for javaw (and tried to paste the exe file here, but seems like github don't support to upload executables, so i put it into an zip) javaw.zip

and i'm not as dumb as to choose a dll file for java

Now that we have updated to the latest version 2.2.0, can we test again to see if this problem still exists? 现在更新了最新的2.2.0版本 可以在测试一遍是否还有这个问题嘛
