First of all, I'm not completely sure if this is the right thread to post this in. If not, please don't be rude: I'm new to Minecraft Forum. Also, I've read the FAQ.
This all started one day when I tried to play Minecraft Forge 1.12.2. The game crashed before the window appeared. I tried playing again, without any mods. Same thing. I rename my .minecraft folder and reinstalled Forge: same thing. I checked the log files, and it appears that nothing is written to them; the game just crashed.
I've tried other versions of Forge, lower and higher than this one, and they all exhibit the same behavior. Vanilla MC plays fine. Note that I have played hours of Minecraft Forge on this computer before this issue arose.
I can't provide a log file since there isn't one. Specs are as follow:
- Ubuntu 19.04
- i7-8550U (4 cores)
- 16GB memory
- Intel UHD Graphics 620
- Inspiron 5000 series laptop

Have you looked for crash reports (separate from the log files, in .minecraft\crash-reports) or the game output (click on settings in the launcher and make sure it is enabled, which will open a separate window containing all output from the game; error codes/stacktraces will not be logged if they use the standard output and not the logger)? There should be at least something being written to one of these; if not, see if there are any files with a name like "hs_err_pid" in the .minecraft folder (these are files created when the JVM crashes, another common reason for a lack of any output from the game itself). The launcher log may also contain a line of the form "process exited with exit code #", where # corresponds to an error code (it should be 0 if the game exited normally).
There are no crash reports from after June 29. However, I just got the output log to open. Trying to run 1.12.2 Forge, the log simply says, "Waiting for log output" but never prints anything. On 1.14.4 Forge, it gives a message (!):
