Client Crashed on Launching

My friend just got a new computer, but he failed to launch the EVE client on his new computer. I managed to get the launcher log file from him, and narrowed the issues down to one log output:
2020-07-12T23:52:37.702Z default error ClientCrash …\src\customwebpage.cpp in CustomWebPage::onProcessFinished : Client crashed with exitCode: 4

what could potentially cause the crash?

Same issue, other exitCode…
Is with me for atleast a week and it driving me nuts, main client seems to be stable but alts are randomly crashing.
